This is not uncommon for not just Biden -- all documents and social media and PR and orders are not written by the actor, so often times the actual authors either become too ambitious or miscommunication moves some thing forward without verification the actor is aware.

But then again, with senior citizen dementia patient Biden, they likely push stuff thru and give him notes later hoping he shuts up. On this occasion he either misunderstood or did not know until the note.

Moral of the story is -- we know he is just a puppet and we let it persist.
