It's possible the real coords are based on a larger coordinate system and get "local'd" for the current map. If the internal coordinates for the upper left corner of different maps are not the same (should be 0, 0 in local maps) then they are probably more global. Figuring out the larger context is the hard part. I heard the BC starter zones for Blood Elf and Draenei are just z-coordinate shifted far below some part of other existing zones. This is also supposedly why you aren't allowed to fly there.
