I'm puzzled by this, too.  Although the overall syntactic framework
for OWL-S is RDF, any time the representational going gets tough we
allow any notation to be used.  For instance, it looks like WSDL-S and
OWL-S have about the same thing to say about representing
preconditions and effects, to wit: use your favorite notation.  As
David points out (rearranging the order of his message):

I imagine that in practice software tools will support only one, maybe
two, notations, and eventually one will become the standard while the
others wither away.
