Substitution

[TwinSears]

I believe we have to look at the intent and not the letter of the rule.

With four players coming in, the player who remained was probably confused. However, the coach knew and was trying to get his player off the floor. Clearly his intent was not to play with six players or to confuse the other team as to who they were defending.

While it is not the officials duty to know who is being substituted for, it is the officials duty to count the players.

In this situation, if I were the other official NOT administering the throw-in, I would simply blow my whistle and hustle the confused player off the floor. No "T" was needed as it sounds like this was the officials error for not counting the players.
