Predicated Theme vs Postposed Subject

Note that both clauses have the same interpersonal structure, though the Subject is realised by a nominal group in the predicated Theme clause, but by an elaborating paratactic nominal group complex in the postposed Subject clause.

Note also that the predicated Theme clause is encoding (the Value is encoded by reference to the Token your good luck), whereas the postposed Subject clause is decoding (the Token is decoded by reference to the Value your good luck).
