SPARQL update question

[Claude Warren]

Is there a difference between

DELETE {
  GRAPH <http://example/addresses> {
    ?person foaf:givenname "Bill" .
  }
}
INSERT {
  GRAPH <http://example/addresses> {
    ?person foaf:givenname "William" .
  }
}
WHERE
  { ?person  foaf:givenname  "Bill" }


and

WITH <http://example/addresses>
DELETE { ?person foaf:givenName 'Bill' }
INSERT { ?person foaf:givenName 'William' }
WHERE
  { ?person foaf:givenName 'Bill'
  }

I believe they are the logically the same but I want to make sure I am not
missing something.
