What is the call?

Agreed. And it's why I included the "assuming the screening requirements were not met" caveat to my answer -- in an attempt to forezstall this kind of discussion.

A "split second" doesn't cut it. I'll agree there's no specific guidance or case play on this, but I'd use something like the "one or two steps for a moving opponent" rule as a guideline here. If A1 move over and then move in the same direction for one or two steps (or such that B1 now has one or two steps), then the contact will be a foul on B1 (if the contact rises to the level of a foul).
