Nor am I. I do know that in San Soo, we do forms much differently than we do practice. Forms are deliberately more exaggerated (flowery, as one of my teachers says), as for example what we call a down windmill block in a form covers the whole front of the body, while in partner practice, it may be a very small circle--just enough to trap/block the incoming. This video shows something similar, so it occurs to me this gent may be doing the form in the manner he was taught, but would modify the moves for real application. A reasonable response. Hard to tell what would be effective in the heat of battle just from this form. I will say the overhead blocks sometimes don't clear the top of the head, and the downward palm blocks (sorry, don't know the Tracy/EPAK name) would seem to redirect the attack right into ones own groin. But all in all, as some have said, I wouldn't judge someone's practice off of one 'snapshot' like this.
