Not the original poster, but if it's what I'm thinking it is: You're reading down a long thread and you've decided you want to stop reading and go on to the next thread. You have to scroll back up to the top most comment for that thread in the post to collapse it. It would be handy to have a way to collapse from the top most comment easily from wherever you've scrolled down into the guts of the thread.
