Abstract
Considering the XXX spin-1/2 chain in the framework of the Algebraic Bethe Ansatz (ABA) we make the following short comment: the product of the creation operators corresponding to the recently found solution of the Bethe equations "on the wrong side of the equator" (hep-th/9808153) is just zero (not only its action on the pseudovacuum).
