I think the claim that "those studies sucked" and the accompanying link were in reference to:

the battle to get doctors to acknowledge that their "clinical experience" wasn't better than simple linear models

The linked comment discusses a few different statistical prediction rules, not just wine-tasting. To the extent that the comment identifies systematic flaws in claims that linear models outperform experts, it does somewhat support the claim that "those studies sucked" (though I wouldn't think it supports the claim sufficiently to actually justify making it).
