Would it be pair programming if two people sit together and one writes the unit tests while the other one implements the code to make it pass? Red person and Green person?

I guess during the refactor stage you would have some sort of design discussion as well. And it might be useful for one person to be the DRY promoter while the other person promotes the YAGNI point of view, or else refactoring can get out of control.

I don't know, but don't think so, that's the same difference between asynchronous and concurrent.
