Quote - Just because some vertices are shared or not shared changes NOTHING with regard to the number of edges.

A minor detail: the edges aren't shared, they just look like they are.  Poser doesn't care about edges, only vertices and faces.  There are two edges there a modeling app, that's what I was showing in that pic - I pulled one of the faces (polygons) away from the other.  This doesn't change any of what you're saying, just it's a rather important distinction for the modeler (the person as well as the app).
