She's an extremely good racer, and you're right there's a lot good going on. But, some of the things that could be better are being aggravated by the drill in terms of letting her inside half get back, ending up in a few turns a little too much on the tails of the skis, etc. In terms of playing around with inclination I think the idea is to let the edge engagement happen more slowly in the top half of the turn...but not to lose the bottom half. The drill as shown imo isn't working on the 2d key part...you're correct that without context one can't draw conclusions as to what the end goal was.
It is likely that very few people who aren't quite yet at her level would benefit from the drill.
