Kneale, great eye. As for the strong focus on hip angulation, well that involves more hip flex, even if it's to the side. Since the hips don't open up much, increased hip flexing would only drop the hips further aft and further inside the turn.
Kneale touched on one issue, I think we need to explore in more depth. The edge change is sequential (review the crossover at 00:14) but it needs to be simultaneous if we are doing parallel turns. Notice the wedge turn entry that occurs as a direct consequence of this sequential edge change. Why is a bit harder to say without Rossy's input but it looks like the age old defensive habit of releasing the old edge platform only after the new edge platform has been established. Wedge entry, seqential edge change, matching after the edge change, hmm mmm...
...sounds like an old famliar maneuver I know. AWC anyone?
There also is a curious difference in how fast the inside and outside skis turn. Normally we see this in slower Wedge Christies but here I suspect it's a lack of effort (to abduct the inside knee and externally rotate that femur) and some in-riggering might be reducing the effectiveness of the current inside leg steering efforts. It's also something Kneale mentioned, BTW. (A useful tip here is to point that new inside knee to where you want that ski to go and continue to do that throughout the turn. Also remember both skis must finish their seperate turns even after the core start moving towards the new turn.) Be patient with that new outside half, you have plenty of time to shape that new turn.
That's exactly why skiing on one ski would be so helpful. White pass releases to one side, no dump the hip and ride the in-rigger on the other side. BTW, Barnes used this activiy to ski from the top of an upper bowl and all the way down to the base lodge during a white out and somewhat cruddy day over at Arapahoe. (Binding problems meant he couldn't use both skis). So you never know when an exercise like this just might be very useful. Other, less advanced actiities exist and I am sure others will post them but I need to run.
Like I said to start this post, Kneale is spot on about the sequential edge change and the hip migration issues. Release the old turn by rolling the ski over until it releases, then roll it over some more. Then steer it by pointing your inside knee to where you want the ski to go.
