It is shown, that the energy-dependence of the chiral based (formula presented) potentials, responsible for the occurence of two poles in the (formula presented) sector is the consequence of applying the on-shell factorization approximation [1]. When the dynamical equation is solved without this approximation, the T-matrix has only one pole in the region of the (formula presented) resonance.
