the fact that neither of your wordings makes it clear whether I actually have to address your comment to get my code merged is much worse than the tone of the first version. like it or not, you are temporarily in a position of power when you are a required reviewer on someone else's change. they need to satisfy you to move their ticket into the "done" column, and you both know it. rather than dance around this uncomfortable situation with soft wordings, just focus on making it clear what is mandatory and what is optional.
