Abstract
We comment on an unconventional factorization scheme which has been recently proposed by Nachtmann and Reiter. These authors propose to take into account the influence of the vacuum structure of QCD by including a correlation in spin and colour for the partons that initiate a hard scattering process. We show on a specific example that such a factorization is either trivial in colour or spoiled by leading twist infrared divergences.
