This has just been discussed in a recent thread elsewhere - can't find it at the moment. I believe that when two flights sharing the same # are in the same area, one of the flights (maybe both), take on a different prefix, which designates it as a 'departing' flight verus an 'arriving' flight. Or something like that.
