I think he's talking about the support aspect. When a group decision is made, the actions taken are often not a group effort. If the group decided to do X but most of the people capable of acting wanted to do Y, you're going to have problems.
Nothing makes me bristle more than having to clean up after mistake that I warned the team not to make in the first place.

I call those learning moments. Then I engage the people that made or caused the mistake and I'll help them clean up, rather than that I'll clean up for them. That way the lesson gets learned and the next time around it will be easier, and works a lot better than 'I told you so'.
