It sounds like a small project where everything can be remembered by everyone uniformly and perfectly and also people with specialty and exceptional talent into one or the other area are laid off, and everyone is uniform in level of capabilities and preferred area of activity (so it doesn't matter who sits with who over what). Sounds too idealistic where it never happens that two come together who are equally weak or even clueless of a big legacy code and it never happens that the session becomes a guessing game. : )
Pair programming is fine in learning but the team of uniform level experts is too much of a fairytale idea to me for a generally useful concept in the complexity of life (and projects). Don't blame the pointed-haired bosses and accountants alone if the variety of workforce and projects, life itself (differences, variations, uncertainties, logistics, economics, ...), speak against the precious pair programming here and there and it will never be a 100% soluion for everyone and everything. Except if you eliminate/refuse situations with opposing aspects rigorously and without mercy of course.
