On this picture, the claim is just that sex is worthwhile if it adds enough variance to make it worthwhile, so you could either reduce costs or increase variance.
(This picture could be wrong though, if the average of two organisms is just more fit on average than the parents and it’s not about variance at all.)
(This isn’t really affected by Wei Dai’s concern above.)
