Looking at the code, it's absolutely all frames on that terminal.  I've
now adjusted the doc string and the manual.

I haven't dug into the code history here, but the code today says:

    (while (> arg 0)
      (setq frame (next-frame frame))
      (while (and (not (eq frame sframe))
                  (not (eq (frame-visible-p frame) t)))
        (setq frame (next-frame frame)))
      (setq arg (1- arg)))

So the doc string of `other-frame' is correct.
