The N*(1440){yields}N{pi}{pi} decay is studied by making use of the chiral reduction formula. This formula suggests a scalar-isoscalar pion-baryon contact interaction that is absent in the recent study of Hernandez et al. [Phys. Rev. C 66, 065201 (2002)]. The contact interaction is introduced into their model and is found to be necessary for the simultaneous description of g{sub RN{pi}}{sub {pi}} and the {pi}{pi} and {pi}N invariant mass distributions.
