yes, it appears that whoever else was sitting with the obamas and the Saids got up and out of the way when the four had their photo taken.
The napkins are still in place in 2 of the 3 spots.
The setting to the woman's left has a bowl, that someone has discarded, the next one has no napkin, a glass of water, and what looks like an unused place setting.
The next one to the left looks completely unused.
So, nobody wanted to sit with them , or no one was allowed to.
