It sounds like you are promoting a God-driven position that never changes; i.e., COM centered all the time over the arch, through every turn (from top to fall line to finishiation). Am I right?
Woah, let's back up that train; that's not my perspective at all. Remember a little thread where we talked at length about pressure moving throughout the turn? ;)
As Warren Witherell said in How the Racers Ski (requoted from Skiing, Dec 1972, p. 142): "Modern skiing is simply a process of standing correctly on your skis--of applying various pressures and edge angle to your skis to achieve a desired performance." Still relevant today, even though it was published more than 30 years before I started skiing.
I used to think "pull back that inside foot" for a number of years. But after receiving some enlightenment on the level 3 course, I'm inclined to feel that pulling back that ski works on a symptom rather than a cause. And if you're pulling back that foot, you must be doing it to avoid some kind of issue. Otherwise you wouldn't be doing it.
My impression is that pullback is typically used to treat the symptom of the inside ski moving forward, often splaying into a reverse wedge. And yeah, you can momentarily pull that ski back and create a better "look". But why not treat the issue rather than the symptom? Form follows function and all that.
I find when people's inside skis are moving forward, they're often falling inside the turn. Pulling back the inside ski only affects the skier's balance through phase 3 (or whatever PSIA calls post-fall-line). Instead, let's fix the skier's stance and balance above the fall line so that the skier's set up strongly for the entire turn.
In the case of slider, that would mean, for me, seeing him in motion, figuring out what in his stance prevents him from turning his lower joints, and figuring out some exercises to help him turn those joints. (I have some ideas, but would need to see him moving rather than a few freeze frames.)
It's actually good to see the inside ski move forward after the fall line; when you create coiling and your hip faces more downhill, it's necessary that your inside ski has moved forward. That's another reason I'm not a fan of pulling back the inside ski. I'm open to the idea of remaining mindful of the inside ski.
Incidentally, was there some kind of PSIA event where pulling back the inside ski was widely promoted as a go-to move? Or are people pulling it over from the PM*S camp? It's not been a mantra of any sort at any of the CSIA events I've attended.
