What drills?
For the other, we can drop it. You're ok with the ends justifying saying anything. I don't think so in education, especially if one's job is to teach the teachers. The concept is to create some understanding, not confusion.
Just a little critical thinking by the team could have changed this.
But, that's my other issue with demo teams. It's mostly about the skiing. If you can bs your way through a presentation, ok. Exhibit A there.
Ok, we seem to be stuck here.
Drills:
1. Get over it - posted by @JESinstr above. Think Shiffrin nails it in her commentary.
2. High 5 - keeping both skis on the snow but pretending some-one is standing uphill 2 ski lengths past transition and the skier has to extend along the skis to give them a high 5 whilst commencing the turn. (Have to be careful skier does not get over-active with the upper body and arm with this one - then again most drills have side effects.)
2. Skating like:
3. Practically anything with a lifted inner ski - if moving in too quickly lifted ski will end up back on the snow
4. Inside out turns - disconnecting the new outside ski from the snow teaches patience. With aversion therapy if not.
5. The no drill drill. Bit long to fully explain but this vid hits most of the points. Early transfer of balance to the new outside ski by flexing the old outside leg and starting to extend the new inside leg. Lifting the new inside heel means having a good platform to balance upon and no way can we move inside too soon otherwise we can't lift the heel.
@Mike King , yep, I expect most of the CSIA L4s I've ever met would agree with the intent. They may or may not agree with the wording as none of 'em mentions the P word.
Never met JDS however he seems to ski pretty well and note his point at 0:48.
Comments re NZ video, separate centre of mass (CoM) and ski paths and weight distribution between skis.
It all depends on what type of turn and what type of release/transition.
You can hang onto the old turn until your centre of mass (CoM) and the skis are both travelling across the hill.
You can also, or rather instead, release the CoM from the turn far earlier (I prefer to do it with an early-release cross under transition), but not release the skis from their path so that your body will travel quickly inside the new turn under its own momentum. It's fun to play with this and see how much earlier (closer to the old apex) you can release the CoM while seeing how much farther up the hill you can continue the skis path without tripping yourself up. I imagine it would be no fun if you pushed the game too far - I'm too chicken to push it that far (given myself a fright or two, but never tripped up).
We're not talking about traversing across the hill between turns. The aim is to keep turns linked. (In CSIA L3 assessment that will get you pinged.)
Otherwise you are on track in that intent matters. I don't see a conflict between this bit of NZSIA and, say, the infinity move. It takes a certain level of competency before we can flex through transition and time the extension of the new outside leg such that we aren't pushing but we are keeping engagement. It was some time in Feb this year when I fully 'got' infinity. It's a wonderful feeling when you've ripped a good turn and now the skis are still pointing away from the fall line, our brain is taking a more direct path down the hill but we know it's ok 'cause the skis are hooked up. And here they are already coming back.
(Of course the post-ski vid means a return to earth... life's a beach.)
