No. A statement can relate to truth-or-falsity independent of its own truth or falsity. Example: You falsely accuse me of robbing a bank. I admit I robbed the bank, due to a threat against my family. Later, my defense counsel discovers evidence of the threat. The admission is still an admission. It grants that the accusation is true, even though it isn't. The evidence pertaining to why the admission is false is also fair game to explain why not to give any weight to the admission, but it nonetheless remains an admission. Same here. The public discourse should absolutely correct the record and establish what the President meant. He should probably issue a clarifying statement. But it doesn't change the fact that he made a statement that, by its own words if not by its probable intent, conceded the truth of an accusation.
