His situation is more of "When I bend my wrist backwards, it hurts". He's using it in a way that is not necessarily good. Yes, it is included. And yes, it may be helpful/beneficial. But if you're having problems with doing things that way, stop.
This isn't a broken leg, its a cut. You keep it clean (ie, don't refresh the front page every five minutes), and you don't poke it. If it was a broken leg (ie, the front page gave you only the chronological order), then there would need a fix.
