In this particular case, the sentence mentioned above is clearer when not taken by itself. In the paper, it is immediately preceded by "We found substantially lower non-COVID natural mortality risk for vaccinated than for unvaccinated persons." That statement clarifies why they suggest that because vaccinated individuals die less from all causes, they likely would die less from COVID too, regardless of the effectiveness of the vaccine itself.

Reply to comment by sw33tr3l33s in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga
