We just discussed this in another thread -

Despite Nevada's creative interp, it is a violation as soon as the player leaves the court on an inbounds play. Clearly if this was an "unauthorized reason" as covered under 10-3-3, there would be no need for 9-2-12. And there can be no delay if you call the initial violation, so the amount of time OOB or where they went while OOB is not relevant.
I think that most agreed that 10-3-3 exists for other situations, but not the inbounds play.
