Not exactly.  Only a difference in a _preserved_ attribute prevents a
hard link.  The files aren't linked because the quick check, which is by
default based on size and time even if times are not being preserved,
failed.  Thus rsync decided that the file's data needed to be
transferred, so it could not hard link to the old file.  If one uses
--checksum or --size-only without --times, rsync is perfectly happy to
make hard links.
