Personally, I think it makes no sense, but the spec says inReplyTo can be a list. Which turns out to matter, because FedBOX uses a list (pretty sure it's a list, not a collection) of posts to capture the entire up-thread reply chain. And Letterbook would preferably understand that, so we have to parse that list.
