Most programs use some kind of "contempt" score for draws, so in a materially
balanced position, they will reject draw scores, so as to provide active play.
In a position like this, they will keep playing to win, having no means to
"realize" the truth. Since this logic doesn't cause losses, there is no reason
for programmers to spend time making programs smarter in this respect.
