Singularities of the scattering amplitude for l = -1 are related to the singularity of the irreducible four-pole network in the Bethe--Salpeter equation. Under some reasonable assumptions concerning the properties of the network, it is shown that the contribution to the asymptotic amplitude due to condensation of the poles is small, providing the poles are close to l = -1.
