Not a north guy, but it's simple... dual verification of those items. Really the biggest thing would be that the systems are powered down and the engines are verified off. I could see just the engines being a dual response.

The next step apparently was the entire list. I'd rather have 2 eyes make sure everything is off.

For 73n: Is pride really so much an issue that we can't dual verify everything is off? Who cares? I'd rather take the safest route.
