Help with an airborne interception

But later I thought what if A3 was still moving after B1 became airborne, then the foul should have been on A3.

Any tips on officiating a play like this? Clearly I needed to be looking at a lot of things at once, but I did not notice if A3 was moving when B1 became airborne.

Nothing says A3 can't be still moving. But, they can't move into B1's path after B1 is airborne....i.e., A3 can't take away B1's landing spot after B1 has jumped. But A3 can still be moving away from B1 or even laterally as long as they were in the path before the jump (think slight lateral adjustment that doesn't change whether there will or will not be contact).
