So, Martin. 
After a closer look I found that indeed GEOS wasn't checking
for duplicates as JTS was. BUT: reading the code JTS seems to
be only checking for duplicates when snapping segments, not vertices.
So this specific case still yelds the duplicated point after porting
that part of the code.

Did you try with JTS ?
