Just saw this, looks like Holyn thinks of it as a punch down, unless she's changed her view since this vid.
I never saw anyone call it a punch down before but that's how I was thinking of it since that's how it first looked to me on the people who keep it more to their side instead of bringing it across the abdomen.
I called it punch down for a year while I was trying to understand it. I even had a bit of a discussion with SW22 about it as he kinda rolled his eyes at me.
Now that I've spend 2 years looking and thinking and talking and studying.
I can tell you "how" to do it, but how everyone describes it is ... well wrong.
Drew is the only one who actually describes it right. he says he "lets his arm fall."
Trying to punch down, double move, or punch through will just make for a shoulder hit without the body.
The trick is learning to do it naturally so its providing an anchor. vs trying to force it. This is also why I'm not a huge fan of the throw your off arm back to create the shoulder load that overthrow teaches. You're spelling yourself out for more trouble.
Pros (and all of us) say a lot of nonsense that isn't actually true. This is one of those statements about a movement that just doesn't end up making sense if you think about it for a minute though no? What would literally punching down accomplish, even in theory?
"double move"
This is what it looks like to feel it in a shadow move. I'm not trying to move my right arm but it wants to move in that way.
It feels like my right scapular wants to retract, but if I resist that by forcing it to stay protracted (trying to keep the upper back rounded), instead it makes my elbow want to drive forward with a little bit of torso rotation.

100% convinced your a slingshot/coach t plant now.
So you are attempting to literally implement the pulley concept? I think you are going down a super wrong path with this idea.
This seems like you are trying to be active in a bizarre way and it might help to throw heavy objects to feel how this isn't what you are after.
"double move"
Holyn was also teaching squishing the bug with the rear leg last year.
She's an athletic beast with not the most efficient form.
Try your punch move in a pool with a throwing motion(or one-arm hammer toss), it's a very weak move. A pulley is a lever with the fulcrum in the middle(spine) so you are getting a 1:1 ratio. When you swim the fulcrum is the rear shoulder or closer to it so the lever is much longer and get more like a 4:1 ratio or something.
Note how Paige's rear arm starts in front of her body and ends up behind it so she levered her whole upper body from it like starting the lawnmower. It's definitely not a punch.

Uli was teaching squish the bug also. All these players who are good players, but cant seem to muster up the podiums are trying to become coaches, and that's all and good, but... They have no clue what they are saying half the time. Uli tries to hard and is a bit washed up as a player overall and is trying to find some use for himself. And they are trading their name for coaching.
Just cause you play good doesn't mean you can tell others how to do it.
I remember some of my first golf lessons when I was young. It was some guy who coudln't make it as a pro-am. And he wasn't super far off on a coaching level, but he didn't actually know how to coach either. he was trying to break things down in to really unecessary movements and stuff, vs letting things go more naturally.
There is no secret sauce, no secret "double move".
I do think there are a few ways for us to utilize our off arm, but its not some magical "punch down and throw 50 further."
The other problem is that the people who are going to try the "punch down" and the "double move" are already people who are not throwing very far for starters, and the over rotation motion you'll gain from the punch down or double move will give you distance. And it will seem like a magic pill. But it's not. Your swing was already so arm driven and not body driven, you're basically getting a short version of spin and throw, but just with the shoulders only.
