The GS09 and Pythia double PDFs (dPDFs) have both been constructed to satisfy (in some sense) momentum and valence number constraints. I compare the two sets of dPDFs to each other and to the "naive" dPDFs constructed out of a product of single PDFs, in the context of their predictions for double Drell-Yan production. I explain the differences between these predictions in terms of the procedures used to construct the dPDF sets. Based on arXiv:2208.08197
