This logic works in the scenario where nobody knows who the original is. It doesn’t work as well when there is a known original, since this difference in subjective experience between the two may be enough to break symmetry in terms of which arguments are appealing, and the analogy to heirs probably works best. I myself favour a default case of equal splitting, since it means we don’t have to argue about who is the ‘original’.
