I'm not sure I understand what you mean... Reading the post he says while messing around with his phone he messed something up so he had to reload the phone. So instead of going back to stock 2.0.1 he decided to give the 2.1 early build a try. For some the 2.1 release he is linking to could be useful, but he is in no way saying we should load it. For most of us we should not load this, but it's fun watching the video. Droid-Life is a very useful site and on my list of go to sites everyday!
