It's saying don't be roundabout trying to play teacher in code reviews and other stuff. IMO code reviews often drag on longer than they ought to, so be direct and clear offering additional clarification az needed. Sometime even use Slack or video meet if that clears things up quicker and only record the outcome on the review. Respect people and their time. Also be open to sugestions and for reviewers not every suggestion is a must, make clear which ones are.
