I think I just got my cue.
This is always a tough one, deciding if it's ILE or OLR, and really something only the skier could answer for sure. Let me start by explaining that ILE (inside leg extension) and OLR (outside leg relaxation) both serve a similar purpose: they cause a disruption in the skiers state of balance that acts to set the body in motion over the skis and into the new turn, powered by the centrifugal forces of the prior turn.
Here's how it works. Imagine a table standing balanced on the side of a hill. Both sets of legs (uphill and downhill) are supporting the weight of the table, and the central balance point resides somewhere between the top and bottom legs. Now swiftly knock the legs off the down hill side of the table (OLR). What happens? The uphill legs attempt to support all the tables weight, but because the balance point is below them the table topples downhill. That's what happens in OLR. The downhill leg is removed (relaxed), all weight is transferred to the uphill leg/foot, and the body topples downhill and into the new turn, penduluming over the supportive uphill leg. If the uphill leg did not provide some resistance/support the body would just pummel into the ground, as that is where the forces acting on it are directed. Remember, if you are balanced on your outside ski, that is the point on the snow where the forces are trying to hurl the body.
Now, ILE. The same basic principle takes place. When you push down on your uphill foot you in essence move the central point of pressure uphill toward the uphill foot. The same result happens as occurs in OLR,,, the uphill leg/foot becomes the main load bearing leg/foot, the skier becomes out of balance, and the skier topples. Both ILR and OLR remove the lower leg from the equation, the only difference is OLR dumps the load onto the uphill leg, and ILE takes the load away from the downhill leg. It's a subtle difference, but one that can be felt distinctly when skiing.
So what do we see when we look at BigE's montage? Well, we can see for sure that there is definitely significant old inside (uphill) leg lengthening prior to edge angle neutral through the transition. Was it ILE? Could have been, but we can't be sure. What ever created the state of imbalance that initiated the toppling, be it ILE or OLR, happened very early in the transition, I'd say somewhere between image 7 and 6 (4ster's #ing system). It was after that initial balance disruption move that extension of the old inside leg continued. That continuance could have followed OLR or ILE.
My guess would be ILE was the catalyst, only because it avoids the load dumping onto the uphill leg that can call for a muscle taxing catch. In ILE the uphill leg takes on load as its getting longer and stronger. But only Benny knows for sure what he did in that instance of time.
The more important issue to take note of is the old inside leg extension prior to neutral. It's a clear contrast to a retraction transition in which very little old inside leg lengthening happens prior to neutral and the hips cross over the skis very low and close to the snow. Notice that this is an arc to arc transition. This is where you will more typically see this extending type of transition,,, and a pivoted initiation is where you will more typically see a retraction transition. Not an absolute rule, but it's the more common pattern.
OK, hope some of that helps. Now I'm back to editing DVD's
