I have changed it to this:

  "If you are using a window system, the previously selected frame may
  be restored as the selected frame when returning to the command loop,
  because it still may have the window system's input focus."

Right, I changed this.

Because the value of `focus-follows-mouse' is only checked if
`mouse-autoselect-window' is nil.

I don't know how to fix the Elisp manual.
