I don't quite understand. I think the idea is that in our frame of reference, two distant galaxies are moving away from each other at a faster-than-light speed. But it doesn't necessarily have to be the case in their frame of reference.
I've heard somewhere that this property applies to the expansion of the universe, which represents a collection of receding galaxies... although I can't vouch for the plausibility of the theory.
