If you're posting an AR that agrees with the OP's, you can very well add on to that same thread. This way, you're adding to the topic of the thread and not trying to make the thread go in another direction. Eg. The OP was a good review on a girl and you wanted to add on you own good experience with the same girl, go ahead and do it. Keep the thread on the same topic "this girl is good".
Conversely, if your take on the punt is vastly different from the OP's, you absolutely should start a new thread. Then you have a separate thread with a different "topic", even though it's about the same girl. One good, one bad.
