Shaq,
If you think about it, the A1 drives hard to the basket from the right wing, and shoots a right hand lay-up. A1's momentum carries him 7 or 8 feet beyond the end line. B2 comes from the left side and quickly grabs the ball after the made lay-up and continues to his left (the side of A1's drive on the lay-up) to make the throw-in in that direction. Lead-becoming-trail moves from just outside lane line on A1's left side in the direction of the throw-in to get a better angle thus moving inside the lane line extended. A1 returns to the floor up his left lane line behind the official in the OP.
