I feel like you were asking a different question than last two asnwered, so here's my 2 cents lol. Say you join server x, only times you won't be able to see someone from same server x is if they are in pvp arenas, raids, or dungeons. They also recently changed it so you may also see people from servers y and z while on your own x server, but only under certain conditions (which I'm not 100% on), but your own server x population won't phase / instance out.
