It is shown that Marinatto's claim [Phys. Rev. Lett. 90, 258901 (2003)] that
the proof of "Bell's theorem without inequalities and without probabilities for
two observers" [A. Cabello, Phys. Rev. Lett. 86, 1911 (2001)] requires four
spacelike separated observers rather than two is unjustified.Comment: REVTeX4, 1 pag
