Yes.  I think I was a bit hasty and wrote that model on the fly while
still suffering from a head cold (a lot better now).  In retrospect,
it does look bogus :)

Sorry for that.

I'm not sure even aboutEach would have solved this particular
modelling problem.  RDF has subPropertyOf, subClassOf but does not
have subResourceOf - you can't inherit resources, or the properties
of them.  

But given my previous error, maybe somebody with a clearer head can
help out.
