This is just one of those unfortunate situations where everything occurred out of order.
The answer was selected as an audit candidate because of its upvotes, which most likely occurred before the question was modified. During a review audit, you're not shown those votes.
When evaluating low-quality posts, ask yourself the following questions:
- Is it spam?
- Is it "thanks?"
- Is it "I have the same problem?"
- Is it an attempt to ask a brand new question, or
- Is it an attempt to answer the original question in any of its original incarnations, no matter how feeble the attempt, even if the answer is wrong?
If the answer to the first 4 is no, and the answer to 5 is yes, it doesn't merit deletion.
