We emphasize the importance of the position dependence of the diffusioncoefficient D(r) in the self-consistent theory of localization and argue thatthe scaling law T ~ ln(L)/L^2 obtained by Cheung and Zhang [Phys. Rev. B 72,235102 (2005)] for the average transmission coefficient T of a disordered slabof thickness L at the localization transition is an artifact of replacing D(r)by its harmonic mean. The correct scaling T ~ 1/L^2 is obtained by properlytreating the position dependence of D(r).
