The article claims that catching up on sleep during the weekend doesn't work. This is most likely wrong information, as shown in this very recent study [0].
As far as I can tell your linked study says that "possibly, long weekend sleep may compensate for short weekday sleep" in terms of mortality but says nothing about qualify of life.
You can catchup/reset but the days you don't sleep enough you'll do worse.
The "very recent study" is just a recent study. It needs to be repeated, critiqued by other researchers and studies, and so on to be verified. Until then it's worth nothing.
The processor, on the other hand, summarized our research knowledge so far, in other words, tons of study results and a large body of knowledge.
