Lindsay, thanks for bringing it on the table.
I would like to kindly oppose this clip to that one

They propose two different approaches.
Difference between the two?
The former stresses on working the drill on side body position, the second clip stresses on waiting a tiny bit for flatter body position, whilst pulling slightly off on the side.
For several reasons, I think your clip is still an important one. It can teach you how to achieve a lot of vertical position without delaying the catch (catching while still being on downward body rotation instead of waiting). It's important, it may in fact be the way I'll choose to continue swimming this year if the technique shown on clip#2 doesn't bring me what I want.
