For two links bounded by an immersed concordance of annuli, we relate the number of the double points of the immersed annuli to the beta-distance and the torsion multi-variable Alexander polynomials of the links. This result unifies T. Kanenobu's announced result on the Alexander polynomial of a link with unlinking number one and the author's result on the Alexander polynomials of concordant links.
