Inbounds Play after time out

[rbruno]

Team A calls a time with a throw in on the endline under there basket to follow. Teams break the huddle and Player A-1 goes to the endline and the other four players are still at the bench on the floor and Team A coach points to me and says go ahead ( hand the ball to player A-1 ). I hand the ball to A-1 and the other players then run around into their set. Is this something illegal for trying to fool Team B into thinking the time out is not over or is this a legal play?
