One point of clarification might be helpful in the scenario.
16 points IF (a big one, too) most likely it can be assumed that the CLOCK reached zero, at the same time as the "buzzer sounded".

But just to be clear, the rule is when the time reaches ZERO, not when the Buzzer sounds.

In the past, the time and the sounds being used weren't always in sync.
I haven't watched closely enough this year to hear if the sound of the buzzer, was sync'd up with the time reaching zero - perhaps someone else can tell.
