Consider you have three systems; A, B, and C, connected like this:

[A]---[B]---[C]

Now consider that A and C are separated by sufficient distance that 
there isn't a network between them.  Finally consider B to be a notebook 
that can travel between A and C.

UUCP makes it trivial to transfer a file from A to C or vice versa even 
though there isn't end-to-end connectivity between A and C.

This is one of the uses for UUCP's store-and-forward networking.

Now consider using SSH to communicate between A & B to carry the UUCP 
traffic and similarly between B & C.

SSH provides encrypted and authenticated transport that UUCP can ride 
across.

I can send a file from A to C with one command.  SSH et al can't do that 
because there is a lack of end-to-end communications.

The other thing that UUCP over SSH provides is asynchronous operations. 
I can cause UUCP to transfer the file in very short order and move on 
with things.  Conversely SSH commands ten to be blocking and require 
other methods to not hijack the controlling terminal.
