I just came across a blog from Phil where he discusses in detail this exact hand. It was definitely enlightening.

Cliffnotes:
He doesn't think Brunson is an angle shooter.
Casinos are split on whether or not forward motion constitutes a bet/call.
Brunson called of his own volition.
The edited video was done poorly and made the situation look more dramatic than it actually was.
