Buzzer-Beater

[Grail]

Worked a game last night with a rookie partner. So, he's looking up to me as the veteran (My 2nd season).

Anyway, he asked about this hypothetical situation:
A trails B by 1 point late in the 4th quarter. A1 drives to the basket, goes airborne for his shot and is fouled by B1. Tweet-Buzzer-Shot. The ball goes in.

My interpretation: The shot can't count as it was released after the buzzer. The foul happened just before the buzzer and must be assessed. A1 to shoot 2 free throws with the lane cleared. OT determined by how many he makes (or misses as the case may be).

Did I get it right?
