Biden says earpiece direction instead of performing it

Biden's earpiece director tells him to salute the marines, watch what he does and says instead.
But notice, more intriguingly, the marines do Not salute their Commander in Chief. Marines follow orders, so their direct commanding officer has ordered them to not salute Biden.

Ladies and gentlemen of the United States of America, I give you your President and Commander in Chief Joseph Robinette Biden. Or is he?
