HBP: Swing or no swing?

Do the actions of the batter AFTER being hit by pitch play into our decision on a check swing? IMO this is a correct no-swing under softball rules: the batter was not striking at the ball before being hit, and the ball became dead. The wrists had not broken, the bat was not over the plate, and the barrel had not crossed the foul line....none of these are official swing criteria, but those are the things I look for. Had the batter not been hit, I'd have probably ruled the follow-through motion as a swing attempt, but I can see he only swung forward because he knew he'd been hit.
