I was wondering the same thing. This is my first update with the SG4 and I never saw a multiple part upate like this while using the SG2. I guess I may wait because I feel safer that way (call me chicken...)
Chicken.... :laugh: Just kidding. There really is no difference in function. It saves a little time but that is all. It won't impact how the setup runs. Just follow the steps in the second post and you will be updated the same as if someone puts all of those together in one tar file.
