Victory is not just "claimed", is normally counted on points.

It doesn't matter whether the position is actually scorable or what the score is. What matters is the agreement of the players. And of course these are rules for professional games overseen by a referee so a sad player cannot just force both players to lose.
The outcome is either decided by the score (this is the reality), by agreement (this would be hard to achieve logically, requiring the definition of special conditions on when a player is allowed to disagree), or by referee decision (again would need logical definitions of his ruling).
I didn't say "both lose" is meaningless (it does show some intention of the rules, and that it's not ok to do risky/suicidal pass to force stop in molasses ko with killing move left on board for example). But from a logical viewpoint it does have a problem so cannot be easily applied. The rules only define how to score and doesn't define when a player is allowed to disagree ("effective move" is vague), especially without requesting resumption.
