I think the reasoning behind a flip flop hub, is that you essentially get 2 gears, by putting a different tooth cog on each side. You can also "cheat", you put a taller gear on the fixie side, and a shorter gear on the freewheel side, for use on those good old Ontario rollers, coast down, then pedal on the way up.
