Double Foul question

[Dave9819]

Here is the scenario:

Held ball called, possession arrow points to Team A.

Team A awarded alternating possession throw-in on end line.

A1 has the ball for the alternating possession throw-in.

Before A1 releases the ball, A2 and B2 are called for a double-foul.

I know we go with point of interruption. A2 and B2 are charged with the fouls, and Team A will have the ball for the throw-in.

My question is, is this still an alternating possession throw-in, or just a throw-in?

I am confused because when we say point of interruption, would we consider the point of interruption the AP throw-in, or does the double foul cause the throw-in to be just a "regular" throw-in, with the arrow not being changed?

Thanks!
