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

i.e. to implement SOURCE we use a bound ?var in
?var.log:semantics log:includes {?s ?p ?o}.
I have explored alternative implementations
but was loosing..
