Comment (by strk):

 With TestOverlay-geos-1051-simp.xml​ both GEOS and JTS SnappingNoder end
 up with 636 noded segmentstrings. Hard to tell how they differ between
 one-other as the output is slightly different in terms of significant
 digits.

 To get you an Idea I'll paste the first 10 noded segstrings for each.
