There should only be a difference if you have a grid with overlap (which I
believe you don't have).  In the case of InteriorBorder_All_Interface,
overlap entities on the receiving side may receive something, which in the
case of InteriorBorder_InteriorBorder_Interface no overlap entities will
receive anything.

I'm not sure about grids with a ghost layer, but I'd guess ghost cells are
included in _All_ as well.

Bye,
Jö.
