Under the all-but-one rule, a foul committed by the offense behind the basic spot is enforced from the spot of the foul. Should the offense commit a holding foul 6 yards behind the basic spot, the spot for enforcement is the spot of the foul. Therefore the offense would lose 10 yards for the hold measured from the enforcement spot 6 yards behind the basic spot resulting in a 16 yard loss. I'm sure almost every official south of the 49th got it right.
