NFHS please, no NCAA

A1 is shooting a lay-up and the ball hits the backboard and the ball remains in its upward flight outside the cylinder. B1 blocks the ball. The official rules a legal play, is the official correct?

If not correct, please site ruling.

Even though I'm certified, I'm attending the first year class as a refresher and this play came up. I thought this would be useful for other newer officials.
