From man emerge
--depclean, -c
Cleans the system by removing packages that are not
associated with explicitly merged packages. Depclean works by
creating the full dependency tree from the @world set, then
comparing it to installed packages. Packages installed, but not
part of the dependency tree, will be uninstalled by depclean.
It is a little ambiguous in that does the dependency tree from the world
set include the world set itself?

No, just tried it. Pick a file from @world and emerge -cpv it.
[root@phoucgh ~ 0]% grep x11vnc /var/lib/portage/world
x11-misc/x11vnc
[root@phoucgh ~ 0]% emerge -cpv x11vnc
Calculating dependencies... done!

Packages installed: 2083
Packages in world: 350
Packages in system: 49
Required packages: 2082
Number to remove: 1
Files in @world should only be wanted because you put them in there, so
you should be able to remove them.
