The latter: the --detect-* options only detect files in the destination
directory, not --*-dest directories.  Modifying rsync to scan --*-dest
directories too would take a considerable amount of additional code.

To accomplish what you want with the currently available tools, you
could prepopulate the destination with "cp -al" instead of using
--link-dest and then pass the --no-tweak-hlinked option implemented by
the following patch to avoid any attribute-tweaking issues:
