I don't think that's quite it. Apple realises there's a problem, and that's why they have the standardised test. I think the real problem here is that Apple's test is insufficient, but they don't know that, so they don't believe their customers when they say they're having still having issues. And that's not reassuring for someone who's just spent a lot of money on a new machine.

Personally, I've never had this issue with my rMBP, but I'm sympathetic with those that do.
