"Drawn Games:

Many games of makruk end in draws, and this is because of special rules in the endgame which permit the disadvantaged player to claim a draw in very peculiar, and sometimes rather complex, ways. "

This means that those special rules apply only when a player is in disadvantadge condition. If there is not such a player, the rules doesnt apply. That is what I interpret, tought I have never played. Better to verify it.
