I'm not sure that's true. It says a pattern ending in slash only
matches a directory, it doesn't say that a pattern not ending in slash
won't match a directory.
However, the patterns are anchored wrongly. Absolute patterns are still
relative to to tree being transferred. So --exclude=/usr/obj when
transferring /usr would try to match /usr/usr/obj, which is wrong. Take
the name of the filesystem being rsynced off those patterns and you
should find them excluded as you want.
The rsync man page does try to explain this: it is a bit long and can
take a few reads, but look at the FILTER RULES and ANCHORED PATTERNS...
sections.

PS Your flags are way over the top. -a already includes -rlptgoD so you
don't need them again. Do you really want -R and I think that knocks
the top-level directory off the files which are unpacked? And if this
is a backup, then why -u? That's for use when you are changing files on
the destination and don't want those changes overwritten, which doesn't
sound like what you are doing. And if it is a backup, then you might
also want -H to preserve hard links.
