Well, yes, that sort of thing is going to cause problems.

From your description of the real-world problem, I thought perhaps that this situation would occur never or very rarely (which of course is still annoying).

One thing you might be able to do is to only remove exactly *one* vertex from A for every "close" one in B.  And if there are multiple close vertices, select the one which is contiguous with other B vertices (or equivalently has the A vertex index closest to other removed vertices).
