In that video he's just illustrating what the "finger spring" and short arm putting techniques look like. Doing it without a follow through like that makes it easier to feel but adding a follow through will help with power and consistency. He did the video becasue it's a difficult thing to try to visualize if you haven't actually seen it.
It looks silly, but I suggest trying it out if you haven't. Once you get that spring you'll find that it's really easy to get a super consistent line. All you have to do is line yourself up right and get that spring and you won't miss left or right.
