This xdm discussion illustrates the reason. Suppose you don't want xdm
running all the time (or on boot), but sometimes you do. You could
possibly do this with several major areas (e.g. network daemons, xdm,
etc.) so that by specifying a runlevel you would easily control which
services are running instead of having to kill/start them one by one.
You could even set one runlevel to be kdm, and another to be gdm (i
haven't used either, but i get the impression they're rather different).
