Flipping the stem gets the bars lower, resulting in a more aerodynamic position on the bike. It may not be the most comfortable at first, but you will be faster in the long run.
As a point of reference for this discussion there needs to be an absolute 'flipped' and 'not flipped' -- just like port and starboard on a boat, left and right can't depend on which way you're facing. Flipped and not flipped can't depend on how the bike was originally assembed.
