So the camera man said stand really close to her even though there's plenty of room around the shot, oh, and make sure you stare at her intently so you can see into her soul whilst feel you breathe on her neck; and he lost all capacity to say no? Or to stand back a bit? He was okay telling someone to watch their tone, but couldn't possibly say no or just stand back a fraction? Sure.
Maybe an inexperienced camera operator, or even an intern, in a rush and no time to reshoot? It could happen.
As for the people being filmed, cameras can distort things like space and shape and distance. So you don't really know how you look, you have to rely on the people doing the filming to tell you because what seem natural can look weird on the screen, and what looks good on screen can seem unnatural.
If he was a close talker all the time it might tell us something but as a one-off I don't think we can draw conclusions.
