   how can the score change without a move beeing made?

Because in the context of this discussion, the "score" is based on the
opinion of the players, not on actual territory calculations.  In this
example given by John, a player changed his mind after his first pass,
which may be silly, but legal.

   If you make the "as-is" score "everything alive" you should never have
   a disagreement.

I think as-is   means  Tromp/Taylor area  calculation,  inclding empty
points OWNED by players.
