That's not what I said.  Of course it's not a logical necessity, but not 
having that feature stops users from using the "repeat" command at its 
full power.

I understand that you believe that having the possibility to change the 
argument between two repetitions is useless.  But it is in essence what 
the OP asked: he wanted both other-window _and_ other-window-backward, not 
just a repeatable other-window.  Other examples given in this thread were 
similar, and IMO show that it would be a very useful feature.
