NCAA PF Enforcement

[Suudy]

At the Washington State/Arizona State game there was a PF called. It was a defensive lineman on the rush was called for illegal hands to the face. My curiosity is on the enforcement.

Down and distance doesn't matter, but ASU dropped back to pass. During the rush, after the ball was thrown but before it was caught, WSU is flagged for illegal hands to the face. The pass was completed for about 10 yards. The enforcement at the game was 15 yards from the previous spot.

Is this the correct enforcement? I'm a Fed guy, and it makes sense, since it is a foul during a loose ball play. The only special enforcement is for RTP, which indicates it is 15 yards from the end of the last run when the last run ends beyond the NZ (and no COP), otherwise from the previous spot.
