xxx is an IRI. yyy is the property (relationship type) denoted by the IRI. You could add another arrow down the middle:

  :g -----xxx--->  {ggg}
   |       |        |
denotes denotes  denotes
   |       |        |
   v       v        v
 thing ---yyy--->  graph

When xxx is owl:sameAs then we have a special case where “thing” and “graph” at the bottom are actually the same single thing, and both :g and {ggg} denote it.
