I think when you try to trick somebody into thinking a wine is something different from what it is, that's very much different from saying we can't tell apart wines at all.
I agree with the general inability of wine tasters to discern nearly as much as they believe, just not this particular example.
Expecting to taste a red wine and getting a disguised white wine means you're not ready to appreciate a white wine. It's a whole different world so no wonder they found it off.
It would have actually been a better call to stick to white wine, no coloring added, and differentiate only with the label.
They've done studies like that too, with similar results.

A similar argument can be made about confusing two types of potato vs a potato and a parsnip. Yes pleasure is subjective, and taste is to some extent. In general there are limits to this effect.
Yes, I could effectively overcook the taste out of both things, mush them into a texture-less paste, and then stuff them full of enough herbs and spices to mask any semblance of their original flavour. At that point perhaps I've won - but then I'm not sure it meets the claim.
But I'd put money that every experienced taster was able to deduce in blind tasting the bordeaux from the (insert other wine type??). Indeed as I understand it from watching Frasier there are clubs which do these blind tastings all the time.
In other words. I may tell you this bordeaux is cheap and acidic, but at no point was I mistaking it for a bottle of Rose.
