I think doing that can be framed in different ways, some more chaos inducing than others.

If you dive straight into poking holes, it might be chaotic. In the other hand if you frame it as "I'd like to ask some questions about why we made this decision the way we did to help me understand it and get me onto the same page as the rest of the team, when's a good time?" This makes it clear your goal is understanding the decision and not changing it.
