I'm not sure what you mean.  I guess the question I was posing with
that axiom is if it is the case that every service (SPARQL RDF
protocol service or Dataset HTTP Protocol service) 'manages' one and
only one graph store or RDF dataset.

Ok, but can any of them be associated with more than one dataset or graph store?

I wouldn't think so.  I've assumed that each service description
document has only one sd:Service instance and (incorporating what
Gregg said about the way the sd:url property is used), the service URL
is

SELECT ?SERVICE
{
  { ?SERVICE a sd:Service FILTER(isUri(?URL)) } UNION { ?ALIAS sd:url ?SERVICE }
}
