Legal play or throw in violation since A1 first to touch ball in bounds as the thrower?

NFHS:

4-4-5 . . . A ball which touches the front faces or edges of the backboard is treated the same as touching the floor inbounds.

9-2-6 . . . The thrown ball shall not touch the thrower in the court before it touches or is touched by another player.

The play in the OP is a violation.
