what it means is: if i'm 100% sighted, go to a page and see, say, the opening times for the local library as a nice flash animation, i should also be able to access the same information (the opening times) even if i'm completely blind. if the flash animation can't be made accessible, then an alternative (text only version or whatever) needs to be provided. i.e., whether i'm blind or not, i still get the same information and (more importantly) the same quality of information.
in the above case, just sticking an alternative description there along the lines of "[a flash animation of the opening times]" does not make it accessible. otherwise a sighted person has an "advantage", as they receive more information from that page (the actual opening times) than blind users.
a bit rambling, but i hope this clarifies the issue a bit.
