Another OBR contradiction? Bouncing HBP

[Buster Light]

Official Notes - Case Book - Comments: If the pitch touches the ground and bounces through the strike zone, it is a "ball." If such a pitch touches the batter, he shall be awarded first base. If the batter swings at such a pitch after two strikes, the ball cannot be caught, for the purposes of Rule 6.05(c) and 6.09(b). If the batter hits such a pitch, the ensuing action shall be the same as if he hit the ball in flight.

Seems kind of surprising to me.... What the heck was he doing in the strike zone and not attempting to swing? Sounds like he was trying to get hit and therefore I would have ruled as you did. Option B. Goes to show how much we know ;-) Guess you just had to be there!
