Comment on "Coulomb corrections to e^+e^- production in ultra-relativistic nuclear collisions"

The qualitative difference in the use of retarded and Feynman amplitudes as demonstrated in nucl-th/0101024 had been wrongly considered in this comment. The concept of the breakdown of crossing symmetry is not effective in the case considered in the adressed article. The technical aspects of the evaluation of higher-order corrections which were adressed in the original comment and their applicability to the total inclusive cross section have been clarified.
