Hi Ross:

It depends on the help-win variable which is defined right above the
call (line 544 of ess-help.el)...

         (help-win (or (and (eq curr-major-mode 'ess-help-mode)
                            (selected-window))
                       (and ess-help-reuse-window
                            (ess--find-displayed-help-window)))))
     (if help-win
         (progn
           (select-window help-win)
           (switch-to-buffer buff nil 'force))
       (if ess-help-pop-to-buffer
           (pop-to-buffer buff)
         (ess-display-temp-buffer buff)))))

If help-win is true, then it does (switch-to-buffer buff nil 'force))
otherwise it does something else ;o)
