"Fresh" blank nodes vs. RDF Merge in Update

All,

I came across the following sentence in the SPARQL 1.1 Update spec:

"Blank nodes in QuadDatas are assumed to be disjoint from the blank nodes 
in the Graph Store, i.e., will be inserted with "fresh" blank nodes."

This sounds like the same as doing an RDF Merge as specified in RDF-MT. The 
HTTP Graph Store spec says that a POST should be an RDF Merge, and it 
equates it to an INSERT DATA, which makes it even more likely that the same 
thing is meant.

Is that correct, and if so, wouldn't it be more appropriate to reference 
RDF-MT normatively instead?

Best regards,

Kjetil
