No, That does matter, because then, if it were back to front, It would be the flag of another country!

p.s. Sorry, I cannot help having a laugh
A reversed Irish Flag is the flag of Cote d'Ivoire! Thing is, It's IMPOSSIBLE to fly vertically symmetrical flags like that upside down as distress signals!
Why not use the 46-star US flag and fly it off Titanic's foremast?
The US flag is one of the world's most complex flags. The game would mess it up A LOT!
Though the idea of a Titanic with all three flags versus one flag based on location isn't that bad of an idea if you ask me. It would be nice to see the White Star house flag off the main mast, the courtesy ensign off the foremast (UK in British ports, US in American ports, and France in French ports), and, of course, the blue ensign on the ensign staff at the stern (the only flag that stays on when not in port), showing up between 8:00 AM and sunset. I know of a PDF where the sizes of the flags were studied lengthily based on photographs and any surviving flags, as well as specified when the flags were most likely flown: http://titanic-model.com/articles/flags/FLAG_REFERENCE_MultiPage_ver2.pdf (http://titanic-model.com/articles/flags/FLAG_REFERENCE_MultiPage_ver2.pdf)
Of course, consider the context! More lag-inducing aesthetics is
just what Titanic needs
But still, for the PCs that can stomach it, it would be a pretty nice feast for the eyes.
