I'm interested in this difference too, because anecdotally post-workout stretching does reduce soreness for me. One of the two studies referenced in the part about how stretching doesn't prevent DOMS actually did find that stretching decreased soreness, and post-workout stretching decreased it more than pre-workout stretching: https://www.ncbi.nlm.nih.gov/pubmed/21735398. But, as the paper authors termed it, the effects were "clinically insignificant" (not the same as "statistically insignificant"). The results still strike me as odd from my personal experience, because it's so predictable that I'll be sore if I lift weights without a 5-10 min cool down afterwards. I'd want to see added research beyond these couple of studies before jumping to a conclusion.
