What is the point of this? I mean, UUCP is/was used primarily for remote login and to transfer files, which both are native functionalities of SSH.

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.
