Boli,

they can be different if you mean this - this is the idea. You use some
parameters or an epsg code (you can look at http://www.epsg.org) to
define the "source" of your coordinates. Because of that you must always
provide the right projection for your data. Then the mapserver can
reproject it to the projection of the whole map. The projection of the
map is free for choice depending on your needs. You can set that to
whatever it should be.

Regards,
Norbert
