They are playing with a 7.5 point komi [1], and so a game cannot end in a tie. Doesn't that mean that there is no distinction between winning and not losing?
[1] komi is a number of points that is added to white's score to compensate for the disadvantage of moving second. When a non-integer komi is used, such as in this match, you cannot have a tie because scoring on the board is always integral.
