As far as I know the shadow topic will stop recieving the new posts after the move, so it should drop fairly quickly from the list
Correct. It allows posters from the thread find it. And since it is not a real tread, but a redirect instead, it will no longer keep being flagged as having new posts, it will no longer be bumped with new posts and will not listed in search results.
