The basic assumption is still placing some kind of ethereal connotation to human sentience by pretending it "returns" provided every single parameter could somehow be duplicated. So no, there is not a standard in nature you can point to where such a situation exists. It's all completely speculative.
It's not that much different than when the creationists edited their material by replacing "Jesus" with "creator" and calling it "Intelligent Design" in order to skirt legal restrictions on forcing their theology in public schools. Same idea, different words.
