Haven't heard of that method, but that doesn't mean much as I'm no expert - but I will say whatever you do, you just cook it at your desired temp till it's tender (which you'll know by how it feels by probe rather than what temp it is), let it rest at least an hour, and eat it. That's basically all there is to it. Salt & pepper is a great way to go, but there are other interesting and delicious variations for rubs.
