The thing is "yum clean all" doesn't often really remove everything. And
CentOS uses delta-RPMs, which don't contain everything. Instead they
just contain the diff's from the old version to the new. So on a yum
update they use the diffs from the RPMs and the data from the old RPMs
to build the "stuff" for the update. Which is why you see directories
there for mod_ssl and other things. It's normal, but I don't like it either.

You can safely do a "/bin/rm -Rf /var/cache/yum" from time to time to
clean up the mess. The next "yum update" will bring everything back that
needs to be back.
