Link constraint of a linked object

I am duplicating a rig in maxscript. One of the things that was done, is that there is an object that is linked to one object and link constrained to another object. It works fine in the rig. When I duplicate this either manually or in script, the object pops to a new position as if the link constraint is overriding the link. The other rig still works. I can't figure out how they accomplished this. Any help would be greatly appreciated.
