There is only one study in this article, and it involves how a group of people adapted to a 14-hour sleep pattern. Other than that, there are no studies of importance here, nothing that confirms concretely that this kind of segmented sleep is effective for humans. It is based on historical hearsay but cannot make a prescriptive judgment. The evidence purely anecdotal. Please be careful in reading things like this that you do not immediately form a blind belief or justification.
