It's a bit complicate to explain, but I will try my best:
Visualize the satellite arc as a rainbow. Your truesouth sat is the one in the center of the arc, which is also the highest sat of the arc.
1. When you set up your h-h mount correctly, meaning truesouth sat at 0 rotation degree. When the motor turn left or right, the elevation of the dish start declining, making it hit all the sats of the arc.
2. In my example SBS6 as the truesouth sats but you pick G11 as your highest sat, the mount will track half of the arc correctly (from G11 towards WEST). But when it turns towards EAST, it will not hit the sat correctly. Why? because the dish elevation starts declining when dish moves towards EAST. BUT the sat between the truesouth sat (SBS6) and G11R have dish elevation even higher than G11R, therefore the dish will only tracks half of the arc as I have stated.
Hope this clear.

I'm having trouble following why the "mount only tracks half of the arc"?
Please help me to understand.
Seems to me that if I use G11 as "highest sat" that the motor should still be able to turn 45 degrees either side of it, rather than half (45 degrees).
When I say "highest sat" I'm thinking that the motor (which is electrically set to 180 degrees, south reference) is installed so that its 180 south is actually pointed at G11.
