The update document is inconsistent about LOAD.

[[ 3.1.4 LOAD
an empty graph being retrieved will not create a new graph in the graph 
store.
]]

This disagrees with the formal definition

[[ 4.3.4 Load Operation
OpLoad(GS, documentIRI, iri) =
    Dataset-UNION(GS, { {}, (iri,graph(documentIRI)) } )

graph(documentIRI) is a function returning the RDF graph serialized by 
the RDF document retrieved from IRI documentIRI
]]

but an empty graph is a legal RDF document and so it does create an 
empty graph. This may be removed but it is not required.

I prefer the formal definition version.
