B1 is entitled is straight line movement down the court as long as he does not move into A1's path. B1's movement is in effect a legal "moving screen".

Show me where a defender is granted the right to a path outside of screening actions. They're entitled to a spot, for sure, but not a path.

A1 can't use an arm to do so but body/body contact can't be anything but a block any more than when two players, one of which has the ball, paths intersect at any arbitrary angle. The moment A1 diverts, B1 IS in their instantaneous path. If that were not the case, they'd never collide.
