Question/Comment on FROM and WITH

Are graph labels lost when assembling a background graph with WITH clause?
E.g. what would I get for this query?

SELECT ?src
WITH <http://example.org/foaf/aliceFoaf> <http://example.org/foaf/bobFoaf> 
WHERE
  GRAPH ?src
  {
    ( ?x ?y ?z )
  }

and what about this one - will it return any results?

SELECT ?x
FROM <http://example.org/foaf/aliceFoaf> 
WHERE
    ( ?x ?y ?z )


If the graph labels are maintained, I see no distinction between FROM and
WITH. If they're not, then example queries such as in 8.1 and 8.2 are pretty
confusing and I'd suggest using explicit FROM/WITH.
