Mesh.Vertices.CombineIdentical Failing on points coincident with World Planes

Any idea why this should be? When I move the points out of plane it works fine...but whenever any of the points fall in the plane the vertices simply won't combine and I'm left with naked edges.

How are you combining them?

I'm appending one mesh to another and then combining the identical vertices thus:

msh.Append(msh_rods)

msh.CombineIdentical(True,True)

Here you can see that all of the vertices that lie on the XY, XZ and YZ planes are being registered as naked because they are actually duplicated/uncombined. But when I move my reference geometry that the meshes are being generated from, the combineidentical works no problem, no naked vertices:

...the other thing that is odd is that I can repair the mesh after the script using the Mesh WeldVertices component...but somehow can't manage inside of the scripting component. I can't find any value in the mesh.weld tolerances that will do it...
