throw in violation?

[wanja]

College game. Team B scores. A2 steps out of bounds along endline followed by A1 stepping out of bounds with ball along endline, A1 passes ball to A2 while both remain out of bounds. Partner later comments that a throw-in violation had occurred since both players were out of bounds before the throw-in started and during the throw-in.

Both NCAA men (7-4-6b) and NFHS (7-5-7) rules allow the privilege of passing to a teammate out of bounds after a score. I can find no rule or case citation that indicates that the privilege is not granted if both players are out of bounds before the start of the throw in and during the throw-in.

Any clarifications or citations?
