Coincidence has to do with position, not normal. Thus, you want to merge 
two contacts with different normals, but the same (or close) contact 
points. The best way to merge contacts is to treat the contact points as 
"vertices" and do "vertex welding" with some large epsilon (say, 0.05 
meters or so).
