-x means "In the GIVEN DIRECTORY, don't descend into any subdirectories
that are on a different filesystem."

So, if you hand the directories bin, boot, and data to rsync, it
doesn't matter if they happen to be on different filesystems. You told
rsync to copy them. What matters is if bin, boot, or data have any
*subdirectories* that are on different filesystems.

For example, if the data directory has a subdirectory, foo, that's on
a different filesystem, then rsync -x won't descend into data/foo.

Does that help?
