Oh, yes, I remember.  This requires not just a flipping of the mapview 
but in fact a full mirroring (similar to the Jason-strip I think).

So if you look at point A you might see either

   cde
   fAB
   lgh

or

   lgh
   fab
   CDE

so while east and west have remained constant north and south have flipped.
