So a good place to start might be to ask anyone who thinks it does, to come up with an example involving mutability and entailment (or consistency). For example, if we have explicit time snapshots, then an inconsistency which appears when times can be inferred to overlap might be such an example.

I cannot check it right now (I write this mail from my mobile) but as far as I remember the RDF compatible semantics of OWL 2 explicitly refers back to the RDF Semantics (of course the 2004 version) in its definiton. To be checked, though.
