It's complicated. Most rulesets (AGA, New Zealand, I believe chinese) say "resume the game". The Japanese ruleset is a lot more complicated. I still don't see your argument. Humans and humans are capable of agreeing on a score with those rulesets. Computers are also capable of following the ruleset and agreeing on the score. Computer vs. human games are not playing by a different ruleset. By that ruleset, the game is over when both sides pass.
