I recently reached 500 rep and gained access to the review system, so I'm evidently new to it. Today I received my first audit, which I almost failed directly as a result of it being an audit. It took what it (or, I suppose more accurately, the up-voters) deemed to be a high-quality answer and put it in the "First Posts" queue. When I viewed the answer in the queue, it had 0 up-votes, was not accepted, and, as I later noticed, had no username, profile picture, rep, badges, or whatever attached. I clicked the link to the question itself and saw the same answer posted by an evidently not new user (17k rep) with 21 up-votes and an accept. I made what I thought was the only logical assumption: someone had seen the answer and copy-pasted it into a new one. I would have flagged it, but then I scrolled down on the question's page itself to view the only other answer, and noticed it was not a copy-pasted version. I then concluded that it was an audit, up-voted the post, hit "I'm done," and received a notice saying I passed. My question is, however, what if I had flagged this post? Would the system have deleted the flag? Would it have counted in my total "raised flags" count, and, if so, would it have been marked as unhelpful?
Rough reconstruction of what the answer in the queue looked like (profile pic was originally a generic person silhouette):
