    "abstract": "In a recent paper [Phys. Rev. {\\bf A64}, 042113 (2001)] S. D\\\"urr proposed an\ninteresting multibeam generalization of the quantitative formulation of\ninterferometric wave-particle duality, discovered by Englert for two-beam\ninterferometers. The proposed generalization is an inequality that relates a\ngeneralized measure of the fringe visibility, to certain measures of the\nmaximum amount of which-way knowledge that can be stored in a which-way\ndetector. We construct an explicit example where, with three beams in a pure\nstate, the scheme proposed by D\\\"{u}rr leads to the possibility of an ideal\nwhich-way detector, that can achieve a better path-discrimination, at the same\ntime as a better fringe visibility. In our opinion, this seems to be in\ncontrast with the intuitive idea of complementarity, as it is implemented in\nthe two-beams case, where an increase in path discrimination always implies a\ndecrease of fringe visibility, if the beams and the detector are in pure\nstates.",
