I didn't understand everyone sitting down/shuffling near the end, unless it was literally just for the visual of them standing back up when GEOTUS said "And we stand for our American Flag!"
Was so odd. There was this kid that stuck out when everyone sat. First the people over GEOTUS's left shoulder, then the right. The kid did a thumbs down at… something, then clapped for something, and then the adults stood back up for the flag part.
Most peculiar thing.
