The '06 GTs came with power-assisted brakes. That means the hand and foot controls are separate circuits from the front and rear wheel circuits, so bleeding is a bit more complicated. That may be the procedure that you have.
The '07 and up bikes have ABS, but no power assist, so the front lever connects directly to the front calipers, and the rear pedal connects directly to the rear calipers. There are still points on the ABS unit that can be bled, but no separate reservoirs that need to be filled there.
If you take your time and bleed it like a normal brake system it'll work just fine. Just don't let the main reservoirs get so low as to introduce air and you shouldn't have to mess with the ABS unit at all.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...
