I think it's important to distinguish between different roles in the URI
lifecycle:

 - For an RDF *author* -- i.e., someone/something writing and publishing
RDF -- the author has the choice of making the distinction between the
landing page and its subject.  If he/she chooses to make this
distinction, then he/she can further choose how to do so, and two of the
options would be: (a) to mint separate URIs for them; or (b) to use the
punning properties technique described in
http://www.w3.org/2001/tag/doc/uri-usage-primer-2012-10-03/

 - For an RDF *consumer* -- i.e., someone/something that reads RDF --
the consumer has no choice about whether the RDF that was received makes
the landing-page-versus-its-subject distinction: it either does or it
doesn't.  So AFAICT, the punning properties technique is not intended
for this case.  In this case what's needed is an after-the-fact way of
"splitting" the resource identity, as described (sketchily) here:
http://dbooth.org/2007/splitting/ 

So it seems to me that the situation in which the punning-properties
approach would be applicable -- the RDF authoring situation -- is a
situation in which the author probably would have the choice of using
that approach or minting separate URIs.
