This is just a replay of the "Oh He's Just An Innocent Idiot" nonsense that was so popular around George Bush. People would say he's an idiot and that he didn't realize what he was doing, and that got him off the hook for the absolute atrocities he committed against not only the people of several countries around the world but also against the people of his own country. Don't give Biden the same treatment; don't let him off easy.

If it was a mistake, it's not a minor one; major "mistakes" like this warrant corrections after the fact, either from Biden directly or from White House communications. Since he hasn't corrected it, it's safe to assume it was intended.
