No - it's just the required muscles aren't keeping his knees out. I think.

Tight "outside of hip" isn't going to be blocking the good positioning here. If anything, he needs to stretch his adductors (inside of hip).
However, the big tell here is that he CAN have his knees out, but they move in under load.
The solution is more squatting and forcing the knees out constantly.
Cheers dude. I'm not disputing what you're saying, just trying to understand it for myself
