All of this indicates that the word "identity" is being used in at least
two different ways here; one as a statement of likeness, and another as 
a statement of "selfness". The copies are identical with the original in
the former sense at least. I see a problem with the resurrection claim
in that if multiple copies are allowed, and in principle they are if
identity is defined only by structure and organization to the exclusion
of the need for a soul, then there is no way that the copies can be 
identical with the original in the second sense.

Yes, in at least the first sense. The problem still remains that killing
one of a set of identical twins is usually considered murder although
by the song analogy his identity still exists. This is the absurdity.
