Well, the description of the 3rd is "... OVER A REMOTE SHELL PROGRAM",
so you're wrong in assuming "(no remote shell involved)". Using a remote
shell will of course imply pipes...

You're missing the "From the user's perspective". the syntax and
behaviour is the same as when connecting to an rsync server, but under
the hood remote shells and pipes are involved now.
