There isn't a rule that states that. The ref can wave him back on at any time.
I thought the rule was, if a player went off with a head injury, they had to wait until a break in play to come back onto the pitch. That allows the ref to assess the player and make sure the injury isn't too bad. I can't be bothered to trawl through FA law, this is what I've been told. If there isn't a rule about it, then the ref can do what he wants and wasn't in the wrong.
