Such a scheme correctly describes subleading soft contributions to multiplicity distributions. However we find that a simple receipt for incorporating recoil effects into the dipole multiplication picture conflicts the collinear factorization and does not lead to the correct DGLAP equation.accepted for publication by JHEP on 21.02.2009; to appear in March 2009High Energy Physics - Phenomenologytext
