I think you are taking liberties with the well defined term 'interrupted dribble'. A more apropos description for your sitch is 'fumble' followed by a touch by an opponent. I would not have a violation here even if the touch were by a teammate of the former dribbler. The only occasion for a violation here is if B1's contact with the ball were deemed intentional.
Don't ask me why, I'm JUSTACOACH, but I'll take a stab. See 9-5-3...Pg 55
