I also don't understand that sentence.. rather I'am sure that "Any variable that is not bound must match another variable that is not bound." The main issue I see with SOURCE is where Dave writes >> SOURCE ?var (?s ?p ?o) >> >> When SOURCE ?var is given before a triple, the variable will be bound >> to all of the known *Graph Names* for that triple. i.e. to implement SOURCE we use a bound ?var in ?var.log:semantics log:includes {?s ?p ?o}.
