Thanks for quoting Policy on this. Upon reading the "actual" text, I don't

Note: "from one toplevel directory into another"
The links are from /usr/lib, which is a subdirectory of a top level
directory. Yes, it points to a top level directory, but that only satifies
one half of the above criterion.
