Indeed, they are like towers of Hanoi.... 
The given link below related to Vector topology is explicit enough :

 />> Boundaries should not cross each other (i.e., boundaries which would
cross must be split at their intersection to form distict boundaries)/

Still, the behavior is a bit strange since on the (top) right of the image,
2 polygons appear to be well-formed - and it should not, as polygons on the
(bottom) right side.

I hope I'll have some more opportunities to run my script on other data,
I'll be watchful ! 
Thanks again.
