The use case for this would be mainly when customers open multiple duplicate chats. The support agent will deal with the issue(s) in one chat window, but the other duplicates (either asking the same thing, or asking other things that have been addressed in the main chat window) will need to be closed. It would be a bit easier for us to close the duplicates without this triggering a rating (which could be rated negatively for a host of reasons), instead of having to reply in every single duplicate before closing.
