 ... to obtain legal guarding position:
 a. The guard must have BOTH FEET touching the playing court.
 b. The front of the guard's torso MUST BE FACING the opponent.

 While I do agree with you in principal on this play, a player that is screening is NOT guarding. They are two different actions. Guarding, as defined, is done only by defensive players. A screener is NEVER required to be facing the opponent.
I do believe the 
intent of screening is that the screener be standing. We call it a block anytime an opponent runs into a screener's extended hip, arm, leg. So, a player on all fours is not in a valid screening position. When the opponenent hits them, I've got a block.
