Mapping to RDF Graphs and reification

In mapping OWL to RDF graphs, to make an annotation on a triple, the triple
is reified into separate subject, predicate and object assertions
similar to reification in RDF.

_:x rdf:type owl:Annotation
_:x owl:subject T(y)
_:x owl:predicate T(AP)
_:x owl:object T(av)

But Tim Berners-Lee is still saying that reification in RDF is broken.
See this message from last year:
http://lists.w3.org/Archives/Public/semantic-web/2007Jan/0088.html

If reification in RDF is broken, and OWL adopts the same method for
quoting a triple so that it can be annotated, does OWL inherit
the same problems Tim has been talking about for all these years?
