Summary
This is the same as File:Osm-defining-the-inside-of-an-area-by-coding-solely-if-it-lies-to-the-left-or-right-of-a-way.svg with the exception that for two (of four possible) ring orientation combinations all possible insides are shown, i.e. for the greenly coded ones this is (from left to right in the graphic):

There are 4 possible cases for arbitrary two rings that do not intersect to define an area on a plane (bbox case). (2x2 sides/ring)
On a sphere, with exactly two rings defining an area, possible cases are halved, (e.g. for the green ones above, both (A) are the same, and both (B) are the same).
But if there is just one more ring (i.e. three or more defining an area), neither both (A), nor both (B) are equivalent cases, i.e. count of cases is doubled, or the same as for the planar case.
