Can confirm, seems unexpected.

bpy.data.user_map(subset=(bpy.data.meshes['Cube.003'], )) in the library file only gives one parent object user, when linked and overridden, the same parent appears twice

@mont29 : is this expected behavior?

That is expected, since the linked Mesh ID is not overridden, it's used by both the linked object, and the local override object...
