By piskvorky:

Yes this is true for cosine similarity, which is the only metric that the Similarity class implements at the moment. But it's not generally true, not for other metrics that I'd like to add in the future, such as information-theory metric (KL-divergence&co). But I guess we can change the docs when (if) that happens...
