Yes.

This is a Prolog-based view of predicate meaning, pretty much equivalent
to Gua\spi's. If we consider the selbri "dunda", its extensional meaning
is the set {(John, pants-1, Irene), (John, pants-2, Irene), (John, shoes-1,
Gale), ...} containing the appropriate ordered triples. The predicate
"dunda be fa la djan." has as its extensional meaning a set of ordered
pairs. 

If the set of ordered n-tuples is empty, there is no true predication
corresponding to that predicate. zi'o blanu means a set of no 0-tuples,
so it is (considered as a full bridi) false.

Intensionally, perhaps. But they have the same extensional meaning: false.
