There don't appear to be projectors mounted behind the screens. They would have to be tracking the screens with separate robot arms, the projectors rushing around the room to keep up. Or they have one or two enormous projectors that can project into the two screens with a mask. They would need to be really hi-rez to do that.
I don't think they are lying. I think they are masters of manipulating the language as much as manipulating technology. Lots of money flowing around in that area, leading to ways of describing the work that maximize the wow factor.
I have seen that kind of thing up close, too.
