  We show that the factorization formula for non-leptonic B decays to two light
flavor non-singlet mesons derived by Bauer et al. in the context of
soft-collinear effective theory is equivalent to the corresponding formula in
the QCD factorization approach. The apparent numerical differences in the
analysis of B->pi+pi data performed by these authors, as compared to previous
QCD factorization analyses, can largely be attributed to the neglect of known
perturbative and power corrections.
