Exception in pattern matching docs bears an incorrect message

[jarroput]

The error message of the InvalidOperationException for this case: (true, false, WaterLevel.High) show the opposite of what is actually the case.

public void SetLowGate(bool open)
    {
        LowWaterGateOpen = (open, LowWaterGateOpen, CanalLockWaterLevel) switch
        {
            (false, _, _) => false,
            (true, _, WaterLevel.Low) => true,
            (true, false, WaterLevel.High) => throw new InvalidOperationException("Cannot open high gate when the water is low"),
            _ => throw new InvalidOperationException("Invalid internal state"),
        };
    }

Should be "Cannot open low gate when the water is high"
