In what sense is a duplicate distinct from an original in these definitions?

A physical duplicate is identical to the original in its distribution of physical properties. This leaves open the possibility that there are non-physical properties which could differ between the worlds. Of course, if you believe there are no independent non-physical properties, then the physical duplicate would in fact be identical to the original.
