Is sub allowed? or not?

Watching a kids tourney this weekend.

Time Out ends, teams returning to floor. While lineing up for for inbounds, while ref still has the ball. Coach A decides to send sub to the table. Ref makes the sub wait until the next opportunity.

I thought that as long as the ball hadn't been given to the inbounder yet, it could happen then (apparently so did the scorekeeper because they blew the horn). But the ref signaled for them to wait, and then gave the ball to be inbounded.

Then I started to question myself, thinking that the ref has the rule right and the reason I don't know the rule is because a coach normally wouldn't change his mind on a lineup after he's had the timeout to instruct the players. And on top of that there were no complaints from Coach A, and it really wasn't any big deal at the time.

Anyway to make a long story short, I was just curious is the ref was correct or not. I keep the book & scoreboard at times and I'm always trying to pick up on things in order to do a better job.
