This is where the Canadian version is perhaps better worded since its code set stipulates that a player who leaves the field of play (with exceptions) must not participate further in the play.

This is probably better than prohibiting returning because (a) it covers the fact that in some cases we want the player to return (to get out of the opponent's bench area!) and (b) we don't want him to affect the play after going out.
