Yea that close-reason is a bit difficult. It's two, maybe three different reasons packed into one.
"Authorship of code: Since Code Review is a community where programmers improve their skills through peer review, we require that the code be posted by an author or maintainer of the code, that the code be embedded directly, and that the poster know why the code is written the way it is."
This close reason deals with is posts that:
- Want a review of someone else's code (like a possible employee that could get hired or not based on the review)
- Don't have the code embedded in the question (whether for licensing concerns or not knowing better)
- Don't understand the code presented, or rather: Want an explanation of code.
Since there is a limit on the number of custom close reasons we can use, these three have been squashed into a single one
