Well, if you take a look at the immediately preceding sentence, you'll
find that this distinction is not made anywhere before:
The function @code{redraw-frame} clears and redisplays the entire
contents of a given frame (@pxref{Frames}). This is useful if the
screen is corrupted.
@c Emacs 19 feature
@defun redraw-frame frame
This function clears and redisplays frame @var{frame}.
@end defun
Even more powerful is @code{redraw-display}:
@deffn Command redraw-display
This function clears and redisplays all visible frames.
@end deffn
All of those functions work by _immediately_ clearing the respective
frame or display, and then marking it for redisplay.
So why change the language in the case that is much less conspicuous
(by not clearing the frame) as it does not cause a large blank window
to show while Emacs is busy?
