Player changes to number in the scorebook ???

Penalized when they occur, after ten minute time limit; A maximum of one technical foul per team regardless of the number of infractions, 3a, 3b, 3c; The infraction occurs when the scorer is advised to add to or change the scorebook; The foul must be charged when it occurs and enforced when the ball next becomes live; Once the ball has become live, it is too late to penalize: A team shall not require a player to change to a number in the scorebook after the ten minute time limit; Team technical foul; A maximum of one team technical foul is charged regardless of the number of players, and substitutes, not wearing the number indicated in the scorebook. Each player must wear the number indicated in the scorebook, or change the scorebook number to that which the player is wearing. Any additional substitutes who become players and require the changing of the number indicated for them in the scorebook will not result in a penalty as the one maximum technical has already been charged to the team for this administrative infraction. If there is no request for change, or if the team member does not become a player, thus avoiding the change, there is no penalty.

What if said player participates, unbeknown to an official, and is then substituted for, and is sitting on the bench? It seems too late to penalize. Am I correct? Can it be penalized the next time the player enters the game, before the ball becomes live?
