Let's say you were in the middle of a side quest and you saved about halfway through. Then you continued it, and you messed up somewhere but didn't want to restart the whole thing. If you have the file copied to their other file slot, you can continue from your last save point halfway through the side quest. You may not run into this little problem, but if you do, there's your way around it.
