  We prove a conjecture by Kreiman and Lakshmibai on a combinatorial
description of multiplicities of points on Schubert varieties in Graszmannians
in terms of certain sets of reflections in the corresponding Weyl group. The
proof is accomplished by setting up a bijection between these sets of
reflections and the author's previous combinatorial interpretation of these
multiplicities in terms of nonintersecting lattice paths (S\'eminaire
Lotharingien Combin. 45 (2001), Article B45c; see
http://www.mat.univie.ac.at/~slc/wpapers/s45kratt.html or
