How did he see into the future to know which work he'd be doing on the next sprint, and how did he also finish the current sprint's work with a bullseye thus allowing the next sprint's to begin and match it?
At my current contract we use "SAFe", "scaled agile framework" which basically revolves around quarterly plannings, but above that is a long term planning of course. (energy industry, scale of hundreds of engineers)
So this sprint shows what you delivered 2 sprints ago, next sprint will be the work you just finished.
