Maybe I'm missing something, but what does "Hide everything but the
top LEVELS levels of headers" mean, if not that all the headers of
those levels are revealed?

Once again, I'm at a loss.  The doc string says

  Hide everything except current body and parent and top-level headings.

IOW, it hides everything, leaving the current body revealed.  How else
can this phrase be interpreted?

To have occur use the last search string, you need to type "M-n" at
the prompt.  I've now clarified this in the manual.

That is already in the doc string.
