Sometimes there's a couple frames in pro slow mo footage where their face goes from being relaxed to looking like a powering up dbz character during the rip. After looking for examples it seems to be not very common or at least an exaggeration so I think I just read into it too much as an excuse to keep pulling.
Just some unsolicited advice and YMMV. Let the whole chain do its work and get as much out of gravity and momentum and rhythm and posture and training and retaining smooth leverage as you can. As you add more momentum/impact force into the plant, more tempo etc. the chain will naturally exert more effort (or you'll be collapsing). But it should still be a smooth flow of motion. If you feel janks, hitches, jerks, etc., you probably want to throw slow enough to clean it up and smooth it out. Like RB is saying (I think), it's not like this is a magical effect on top of the rest. It's mostly just what happens as part of throwing when you power up.
Now just some general reflections. Personally this is what the biggest benefit of slowing down to momentum/effort levels and maximizing them has gained me recently. As soon as I hit a certain level and feel or see some jank, I slow down a bit and work in that range. I feel less and less like I'm working hard the day I'm throwing. Sometimes I'm sore the next day in muscle groups that were underdeveloped and legitimately need to do some conditioning. Upper right pec area takes some stretching. Recovery cycles improve over time as I've gotten smarter. There have been cycles of this especially the last few months after shifting more of the power burden on the strong muscle groups in the lower body and core. It always feels easier at a given distance over time, and overshooting "for free" becomes more common.
“
I gotta say I am shocked how much more effort it takes to throw seventy mph than sixty. That’s like a big jump. Forty to fifty: easy. Fifty to sixty: easy. Sixty to seventy? Next level.”
-Former world distance record holder Simon Lizotte
I think it would be weird to say that a full power drive does not involve effort in the context of the form.
Rhetorical questions: are you already moving like this? Why does it start to feel exponentially more effortful to Simon at 550'-600'? Will that threshold be the same for everyone? Why or why not? What kinds of abilities does a body need to do this? How can you work on it?
For the curious

I fell into some old bad habits focusing on not doing instead of doing but here's me today 330' diamond 171g hyzerturnover and a 300' teebird3 flat linedrive. First gonna work on keeping my weight a little more towards the target I fix this easily if I focus on it I just forget. Can pretty much throw my previous max max distance on at will with better consistent nose angle (FINALLY). Don't know how much more work I'll put in as I plan to just continue to play rec and have far surpassed my original goals when I decided I really wanted to learn. I think I'm more addicted to working on throwing then I am playing the game though.. My girlfriend and I are constantly setting new bests on every course we play and today she felt the heavy disc too. It was fleeting but I am so excited for her.
Good to hear it's going well on your goals! Can't help but offer more unsolicited advice. I'd suggest you don't lose the loose, pendulumy rhythm you're developing there. Keep working on syncing up and tempo etc.
I personally won't gatekeep your steps & they can help you achieve a flow and rhythm, though mechanically I would point out that you are losing a lot of leverage and leaving a lot from gravity on the table there. Posture can improve (switch from power stance to athletic stance, relax at the spine), pocket can become less flat and shoulder could be going more internally rotated at the shoulder, tilted axis could develop, you can land and swing more compressed on the plant leg as part of your shift and so on. That rabbit hole goes deep. If you are taking it slow on your own for now, might suggest that if you want to throw that way you work on squaring up that rear foot and work on "shifting from behind" like Kennets is suggesting. Maybe play with the seabas door frame drills. Look at The Hips thread and try to understand what golf can teach you - that also explains a lot of the jargon. A lot of the ideas from those drills and others are like compound interest over time even if you struggle with them at first. Expect ups and downs. It's ok.
Watch all these pumps and throws and try to see and feel what they have in common with the generous basement man.
Rhetorical questions: Why is that big circular motion he's doing the same as what they're doing? Why does it scale up to more power if you retain the form but scale it up with momentum and gravity? Why is this hard for people to see and do? What did swimming and baseball earlier in life give him?
Why is Gurthie overthrowing this 315' hole with a slowbie for the same reasons?
Should you question it? Or should you just do it?
