edit: maybe not "without physical copresence"

I believe something similar happens when musicians improvise/jam, especially Jazz:

Yeah I was about to mention this, or really any other highly synchronized activity with a degree of improvisation involved. Very cool feeling doing this kind of thing.

I think the point of studies like this using a video game, though, is that it's a lot more reproducible.

Without physical copresence?

There's no reason that isn't testable..
