The documentation also says that

  The previously selected frame remains selected.  However, the
  window system may select the new frame for its own reasons, for
  instance if the frame appears under the mouse pointer and your
  setup is for focus to follow the pointer.

so the current buffer may change (as described below) in some cases.

The documentation of `select-frame' says

  Subsequent editing commands apply to its selected window.

which inherently means that that frame's selected window becomes the
selected window.  Selecting a window WINDOW means to assure that

  If WINDOW is not already selected, make WINDOW's buffer current
  and make WINDOW the frame's selected window.

Which doesn't mean that the documentation can't be improved ;-)

It's not related.
