So the hierarchy is:
Head (rigged for mouth)_______
|| || ||
Rig_base Rig_Base_src2 Rig_base_src3
|| || ||
Comp 1 Comp 2 Comp 3
You can see that even though you're copying the rig base, that every copy is still referencing one copy of the "Head" comp. Duplicating the "Rig_Base" comp does not create duplicates of the comps it's dependent on.
With that logic in mind, the "rig_base" is not the true base. Perhaps "head" needs to be expanded back into "rig_base" for proper usage and full duplication.
It's a bit hard to find these issues using AE's flowchart (I don't know if there is a trick to see more than one comp at a time) but it's just something you have to be aware of. You can test for dependencies by sticking suspected comps into a single comp to inspect it with the flowchart.
