hmm, I use the sameClassAs to mean classes in different ontologies 
are actually the same as part of out ontology mapping work, and I 
notice other examples of markup that does the same.  i.e. I often use 
things like

ont1:Car owl:sameClassAs ont2:Automobile;

sameMembersAs would not seem to me to make sense here, and 
sameExtensionsAs, while probably technically correct, is way too 
geeky for me to support (or, more appropriately, requires too much 
knowledge of logic to decide when to use).  I would call this one of 
those "if it ain't broke, don't fix it" situations and leave it as it 
is.
