IAABO Refresher Exam #17

[SNIPERBBB]

ART. 6 . . . The opportunity to make an alternating-possession throw-in is lost if the throw-in team violates. If either team fouls during an alternating-possession throw-in, it does not cause the throw-in team to lose the possession arrow. If the defensive team commits a violation during the throw-in, the possession arrow is not switched.

The way it's worded to me means any violation by A loses the arrow. If NFHS said "committed a throw-in violation" or "violates the throw-in" it would be clearer if they intend for A to not lose the arrow here.
