isearch-beginning-of-buffer changes the direction to 'forward'
because it makes no sense to keep it 'backward' - there are no matches
before the first match.

But I agree that when the user called scroll-up-command
then it makes more sense to change the direction to 'forward'
to be able to navigate the matches forward from the top of the next screen
(as opposed to keeping the backward direction to be able to quickly
go back that is less useful).
