I think the authors are responding to a claim that AI is doing this: look, we taught them geometry, and now they know calculus! GP is saying that it's not a true zero-shot to have a separate test and training set, because the classes overlap. Similarly, the authors are saying "true zero-shot" is basically not happening, at least not nearly to the extent some are claiming. So everyone here, including TFA, are all kinda doubting the same claim (our AI models can perform zero-shot generalizations) in different ways, I think?
