Something about everyone's positions, e.g. the 4 children in one line closest, then Fauci with Zero leaning out a little also seem like one line, then the people in back--it looks a little like a 2 D game where sprites on overlapping planes give an illusion of depth, but your brain knows it isn't really 3D. I think it really is 3D and just a chance composition that makes the groups look stacked and fake.
