This is true. Once his effect has resolved, it's permanent for the entire match. It does not matter if he leaves the field in any way after that. As long as his initial cast resolves, they will not be able to play the card you named.
Thing is, if you name fire, then they can no longer player fire and by extension, they can no longer play ice because ice requires you to play fire first to play it.
This is wrong, on all accounts. Firstly, if counsel of the absolute leaves play the opponent can then cast the named card. Nowhere on the card does it say "rest of the game" much less "match"; it works like this because the effect that prohibits the action is no longer on the battlefield. Secondly, if your opponent names 'give' you can play 'take', however you can no longer cast 'give//take' as a fused spell, you do not cast give in order to cast take when casting as an individual spell. Please make sure you know the actual rulings on cards before you tell people otherwise.
Edit: I posted this as soon as I read the persons evaluation, turns out in the next post, someone already cleared it up.
