I think the idea is that the empty set is equal to itself so something t= hat evaluates to "nothing" is equal to something else that evalua= tes to "nothing".=A0 e.g. "roda poi gerku je mlatu" =3D= "noda"=A0 therefore=A0 "ro da poi gerku je mlatu cu broda&q= uot; is true for every broda in the same sense that "noda cu broda&quo= t; is true for every.... wait, that's not true so I dunno
