Yes, true.  The point was about getting something similar to the triple:

<> <...homepage> <http://www.w3.org/>

that you lose with you have both @property and @rel on the same link.

With @typeof, the link target gains a type triple.  It isn't the same
graph but you are able to have the relationship of the document to the
linked page via @rel and the "kind" of the link via @typeof generating
an rdf:type predicate.  So, the loss of the @property generating a
homepage predicate isn't a big deal because it generates a different
triple that can be used to gain similar information.

In the end, it may justify the status quo.
