The "Uses the latest backup" thing just means that the latest backup is 
_suggested_as_the_default_ when Emacs prompts for the second file name.  
There's nothing in the world that prevents you from editing, say, 
"foo.bar.~123~" into "foo.bar.~1~" in the minibuffer when you are at that 

By contrast, I'm quite sure that the special meaning of the values 1, 2, 
3, etc. of ARG will be remembered by exactly 2 persons in the whole world: 
Dan Jacobson and the programmer who will implement his suggestion.

In other words, too much flexibility is not necessarily a Good Thing.
