Good point. The article is a bit disingenuous in calling it the "eight-hour solid sleep myth". Matthew Walker in his book on sleep (that's referenced also in the comment you link to) points out, for example, that a lot of learning tends to happen in the latest stages of sleep. So, 8 hours of uninterrupted sleep might well be better than 6 hours + 2 hours siesta.
