What's legal with a 2nd inbounder after a made basket?

[jayedgarwho]

What's the correct ruling here?

After a made basket, the nonscoring team (A) runs a double-inbounder play to break the press. A1 takes the ball out of the net and stands OOB behind the baseline. As the five-second count begins, A2 is in-bounds. A2 then dashes across the baseline out of bounds, and sets both feet OOB before A1's pass gets to him. A2 then inbounds the ball (running the baseline first if necessary).

Legal?

NCAA Rule 7, Section 5, Article 7A says "Any player of the throw-in team may make a direct throw-in or may pass the ball along the end line to a teammate behind the end line."

Are the last words of that rule normally interpreted as:
(a) "to a teammate who is behind the end line as he receives the ball" or (b) "to a teammate who is behind the end line when the play (that is, the 5-second count)begins"?

Any different result under NFHS rules?
