If you have to ask i don't think you will be able to do it, it's not easy to resolder such a tiny component. My bets advice to you is get an old circuit board, I use a RROD Xbox 360 and practice soldering onto it.
That video didn't show how to do anything. However, I just started looking into this but I imagine you wouldn't actually "solder", you'd use a heat gun. Any time there's multiple solder points, it's usually best to use a heat gun to soften the solder.
