That is some good skiing!
It's hilarious how the narrator misinterprets what is actually happening throughout the clip.
I've posted this a couple times before here on Epic, but it well exemplifies what I'm talking about...
Imo, you got it 1/2 right, regardless of what the narrator claims to be happening.
The skier extends into and through the turn finish, if his knees flex, it is because of compression.
When his toe piece reaches the top of the bump or bump face, he does proactively flex to release the turn and force his tips down the backside.
When you say you bring your heels up, you are proactively flexing or holding a flexed tension and forcing the tips down. This is great and what you should be doing.
At 45 seconds the narrator has it completely wrong, claiming the skiing is flexing his knees to clear the bump in front of him.
The skier has actually launched weightlessly at the previous turn finish and is floating in the air over the next bump, he is flexing his knees not to absorb anything, he is flexing to brings his feet back under him and simultaneously opening his ankles to drive his tips down to regain snow contact.
This guy is a very good skier from what I've seen and snaps several turns on the tops that are, well, Epic.
An interesting movement happens at 1:11 / 1:12, the narrator claims the skier "streches" down the backside to regain contact.
While I totally agree the skier is attempting to regain snow contact, I believe the narrator thinks he is proactively extending or opening his knees to make them longer to become some sort of "shock absorber" and is reaching for the bottom. This is an illusion and wrong. He will actually continue to flex his knees into the trough below as he prepares to extend into the turn and turn finish.
This is an important movement, often misinterpreted and a key to advanced mogul skiing. Patiently floating down the backside.
The skier's knees at this moment are actually under flexion tension (hamstrings contracting or slightly contracted), he gets "longer" because his hips have totally opened/ extended as he does the pelvic thrust and his ankles completely open as well to force the tips down. His knees do open, but it is due to his muscle memory keeping him balanced and compensating, not because he is proactively extending them. He's trying to pull his feet backward as you describe while floating down the backside.
if you are proactively flexing or "pre jumping" the bottom of the bump to absorb the terrain, you are initiating your turn with a pivot (similar to most world cup bump skiers), the skier in the video is consistently extending into and through the bump or mogul face at the turn finish and does not proactively flex / retract until his toe piece clears the apex or high point.
Again, very good skiing Imo.
