The difference is that nothing actually depends on xfce-base/xfce4 - the
packages that were listed depend on packages that have names that *start
with* "xfce-base/xfce4" (such as "xfce-base/xfce4-panel").  The
- --depclean output says that you have no packages currently installed
that depend directly on "xfce-base/xfce4" - not that you have no
packages install that depend on "xfce-base/xfce4-panel", etc.
