Hmmmm.

Can you think of a situation where a shared edge between two body parts (Chest and Right Collar), where a shared vert has exactly the same XYZ but different deltas for the same morph?

Chest -0.0453279986978 0.620618999004 -0.0246409997344 Right Collar -0.0453279986978 0.620618999004 -0.0246409997344 (0.0021, -0.00229, 0.00091) (0.00215, -0.00238, 0.00093)

They're close. But not exact. I can always force them to be the same. But I want to understand why they're not. Shouldn't that play hell when the morph in activated???? O.o

The two (right and left) collars:

They are mirrors of each other. The order is nicely convenient. Probably something blender does and poser just reads them in order from the OBJ file?
