I'll bite. Look at his old inside leg at the red gate.
His old inside knee is high, that old inside hip low. Torso
is tilted inside the old turn, with old inside shoulder low.
By the next frame, that old inside knee is lower relative to the hip
above it. That hip has moved higher - the leg has lengthened.
The inside shoulder is moving up.
By this next frame, that old inside knee is even lower
and its hip is up farther, about level with the old outside hip.
He is raising his old inside shoulder, or allowing it to raise.
The torso is tilted downhill more than the hips.
By the next frame, which Razie originally posted,
he's definitely toppling. The new inside leg is airborne.
So what's the mechanism? Did all this happen because he
lengthened his old inside leg, moving that side of his body upward?
But he's also shortening his old outside leg. Look at this 2nd frame
again. Even though the old inside leg is lengthening, its ski is airborne.
Whoah, that lengthening leg is not moving his upper body upward if it's
not planted on the snow, no matter how much leg-lengthening just happened
since the frame before this one.
It's got to be the release, the shortening of the old outside leg,
that's brought up his old inside half. He's lengthening that old
inside leg to try to maintain contact with the snow.
So my answer is that the shortening of the old outside leg,
Outside Leg Release (OLR), generated the initial movement
of his upper body that these frames show. It might also be
helpful to say the CoM was released, and its momentum
contributed to where it went.
