You understand it wrong.

system (or @system for portage versions that support sets) consists of the 
minimum collection of packages for a gentoo system to work at all. It is 
wholly inappropriate for even a profile to add kde to @system - even the kde 
profiles. All those do is set USE flags and an environment suitable for KDE to 
be install, the profile does not cause KDE to be install. You still need to 
emerge kde yourself.

Proof:

The contents of @system are defined by the various files called "packages" in 
the profile dir. But:

nazgul profiles # find . -name packages | xargs grep kde
nazgul profiles #

There is nothing you can do with USE flags that will cause stuff to be added 
to @system. That is not how it works.
