As described, that example looks to me more like an illustration of the misuse of dc:creator than of owl:sameAs.   If :someTerm and someOtherTerm really denote the same thing, and then according to my reading of owl:sameAs semantics,

    someTerm dc:creator "Bijan" .

means *exactly* the same thing as

    someOtherTerm dc:creator "Bijan" .

so I don't see any inappropriate loss of information.  Am I missing something?
