The Soyuz flights support three, the ISS isn't only supported by Russia and the US alone, so the third seat varies in nationality a lot.
The new American crew spaceships support up to six seats, but I don't think the ISS has capacity for more than six and they're not replacing the whole crew in an instant.

I read it as an exclusive thing, Russians flying on the American rocket and vice versa, but i guess there's more than two people on a flight.
