The special enforcement relates only to fouls during the kick. For example, a personal foul committed by team A during the kick, illegal touching in team B's end zone and recovery by team A at B-10. The foul can be now enforced from B-20, making it 1st and 10 at B-35, instead of 1st and 10 at B-25.
In the AR, the foul occurs during a normal running play, so it is enforced by the usual 3-and-1. The language could be better, as the illegal touching doesn't really come into play after team B elects to enforce the penalty. If the facemask occurs at B-4, team B could (and would) elect to take the illegal touching and take the ball at B-20.
