I don't think that it is true that the identity of an anonymous resource
is given by the fact that only identical properties are present in the
model. If two resource have identical properties they may be equal
(owl:sameAs) or not independently of whether they are anonymous or not. 
I think the open-world assumptions applies also for anonymous
resources, and distinguishing properties may exist even if they are not
contained in the present set of triples (since the model is not a closed 
world I cannot assume the identity of the indistinguishable).
