That is unrelated work by a different team. The merits of AF2 have been demonstrated already and accepted by the community (which has reproduced those results both theoretically and experimentally) although the community is still arguing about just how good AF2 (and its descendants) are. I agree the chemistry paper does not look g ood but it's hard to say yet. Like I've said elsewhere DM and Google Researchers are under huge pressure to make their results look as good as possible. Already people have serious concerns about another Google paper using ML for IC layout.
