Comment(by Olivier80):

 No, I attached a second image showing that outer ring is self crossing by
 moving slightly one point to the left. This "hole" is there in the image
 because the winding number is 2 in it.
 Anyway, the buffer of the input linearing should not be what we see in the
 first image.
