The indent for the fold start and fold stop marker needs to be the same.

In your example the indent is zero for both the start and the stop  
marker (both in nesting level 1 and 2), thus it works.

In your next example you change the indent of the outer group to 1,  
but it is also changed for the stop marker, thus the indent is still  
the same for the start and the stop marker.
