I am trying to find connection points for an assembly and I thought I could use the mates as a way to export points/lines of how various subassemblies and parts are connected.  I came across the idea of using EntityParams Method from IMateEntity2.  I am confused as to what the "Point" values are.  From the documentation:

• pointX is the X location of this mate entity in the assembly model space
•    pointY is the Y location of this mate entity in the assembly model space
•    pointZ is the Z location of this mate entity in the assembly model space

If I look at an active coincident constraint, within the top level assembly, I get two entities.  When I look at the "Point" values for each entity, shouldn't they have the same X, Y & Z coordinates?  They don't.  What am I missing?

Here is an example output from the "Get Mates and Mate Entities Example":
