Well, it doesn't even perfectly preserve the original, so I fail to see what else it could be but a copy.
You might argue that for some reason the time-derived copy is more important than an artificial copy, of course, but why?
Why is the time-copy even a copy though? If we call some A a copy of some original B, then we have to have reason to associate A with B (if A and B are paintings, the one is a copy of the other if it closely resembles it, say). What association does EpiphanyA at t0 have with EpiphanyB at t1?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
