But the case play you quoted doesn't make that distinction:

10.6.1 SITUATION C: B1 is standing behind the plane of the backboard before
A1 jumps for a lay-up shot. The forward momentum causes airborne shooter A1 to charge into B1. RULING: B1 is entitled to the position obtained legally before A1 left the floor..... However, if B1 moves into the path of A1 after A1 has left the floor, the foul is on B1. .... (4-19-1, 6; 6-7-4; 10 Penalty 2, 5a)

The only distinction being made in both cases is whether B1 obtained the position before or after A1 leaves the floor.
