how to see Goh's head punch ground throw

This is probably well known, and may or may not be that useful in the grand scheme of things, but I just discovered it today, and thought I'll share it with others.

If you do Goh's throw with Goh's face near the wall, the opponent will bounce off the wall and land face down, side towards, and instead of his neckbreaker ground throw, you'll get to do one of two ground throws

a) Goh pulls on the arm while flipping the opponent over, doesn't look as cool, and I don't think it'll be good for Oki since enemy is face up?

b) Goh bends the enemy's arm back sharply at the shoulder and delivers a punch to the back of the head. Very cool.
