Well, this back and forth series between you two was enlightening.
So my questions was originally the same as Slowplastic's, as in "doesn't Philo/Oakley/Barry violate the inside swing drill?" The inside swing was very helpful in adding power to my throws but I'm guessing that's just because it forced me to stand more upright and not lean over so much (like a folding lawn chair, right?)… With the above posts and playing around with the more "lefter"/wide through the wall back swing in my office, I think I get what you're saying:
So the forward pump gets the pendulum started (and seems to help give the disc its own weight) and then, in the transition, which I understand as when you're doing the equal and opposite backswing and leading with butt into the plant, you resist the upper arm collapse. Then plant and allow lower arm to enter power pocket. Then smash that long connected lever. And, yes, this totally makes it more like my FH, like you were saying slowplastic. SW has said they are the same before but I don't really think I've ever been able to make BH feel connected as one big unit through the shoulder, like it does in FH. I'm excited to attempt to adopt this. I'll probably really suck the next few outings.
