@DarkCygnus The question in the title says "comments ON their code" not "IN their code". I hadn't noticed the review tag until you pointed it out, but, yes, that is another reason why I think they were code review comments.
And yes, I do agree that the question needs clarification as well.
Reading some questions makes you wonder.... how do people get to be in senior positions when they cannot even describe an issue adequately, let alone resolve it.
