The clause "if c migrates from bearer d to another bearer e than [sic!] a copy of b will be created in e" rules out the possibility of any generically dependent continuants that can migrate from one IC to another, but can only inhere in one IC at a time.  The word ‘copy’ is too specific to concretizations of ICEs.  But there are other GDCs that are not ICEs.  

Claims and obligations are GDCs (they are obviously depending on a bearer, but they can migrate) that are concretized as roles (a subtype of specifically dependent continuant, which is allowed here).  If transfer ownership of my car to another person, I do not copy that role where the copy now inheres in the other person.  Rather, my role is destroyed and a new ownership role is created that inheres in the other person.

So ownership can only be concretized in one role at a time.  There are no copies.

Barry already put in a change in the sentence "Generically dependent continuants, in contrast, can in a sense migrate, for example [previously "namely", MB] through the process of exact copying which allows..."
