1. After it's less than 21 days before departure, most of them charge extra for you pouncing upon that (unless you have enough status).
2. Just because you can grab outbound wihin a week of departure doesn't mean you can grab the return part then nor does it guarantee that you'll be able to grab the return part later. So how do you use this for a round trip if you know you have to return at a certain time?
(It's of course exactly because they know most people can't use it at that point that they release inventory at that point!
