Pass hitting player and going through basket

[Dave9819]

So, would 2 points be awarded in this scenario:

A1 shoots the ball from behind the 3 point line. Ball has been released by the shooter and time expires as the ball is in the air. Shot falls short of the basket, bounces off of B1 (head, shoulder, arms - doesn't matter) and goes through the basket. 2 points awarded because the try for goal ended once the ball was below the rim? It is still a live ball, correct?

Same scenario, but instead of hitting B1, it bounces off the floor and into the basket. No points since time expired, correct?
