I do have one of those split outlets.  The reason for it was to keep the
two sump pumps on their own dedicated circuits.  I have never took that
outlet apart to see how it is wired (as I have had no reason to) but that
is how the electricians installed it.

At least I now know that I need to turn off 2 or 3 breakers to get the
whole house.  ;)
