Adjust to where?

Either to the next or previous character starting a line.

Who calls set-window-start there, and why do they set window-start in
the middle of text that is hidden?

There is no need to call it explicitly. Part of a function might be before the window start, and part after. If one evokes hs-hide-all (to which fold-dwim-hide-all delegates), the same thing will happen.
