Um, are you concerned there is an extra header on the board? Not really a problem, they have just told you that pin is ground. Doesn't have to be used.

It is probably there for the relatively uncommon, these days, three pin power LED. They used to do that to prevent people from getting power LED and HDD LED mixed up. That is actually why you have the Power LED as two individual wires.
