No, I'm sure they're all aware, but mentioning cheese dust on fingers alone isn't a characteristic that automatically brings him to mind. If that is cheese dust in the gif, I'm not familiar with a kind that's eaten out of a pan. Something like "Better hurry that pedantry up, your breakfast burrito is congealing rapidly" might work.
Regardless, the person your comment was directed at didn't seem to take it the wrong way, so no harm, no foul.
