We analyse two consequences of the relationship between collinear factorization and kt-factorization.
Firstly we show that the kt-factorization gives a fundamental justification for the choice of Q^2
done in the collinear factorization. Secondly, we show that in the collinear factorization there is an uncertainty
on this choice which will not be reduced by higher orders. This uncertainty is absent within the kt-factorization formalism.
