Well chatting about keeping Noh a secret or not inside of Ru makes less sense than talking about it in the moment.  People can overhear you which invalidates the entire discussion, a team should have their gameplan ready before they hit the field (Ru).  Everything that happens is in response to our actions.  We wouldn't even be in this situation if we went towards Uta or the bandit path, which is why the team discussing routes, strategies and decisions is important.
