So you can change the front or rear independent of each other, or both at the same time by leaving the lever in the center position.
That doesn't make sense though. Brake balance is by nature a relative measure. Now granted, il mio italiano non e' il meglio... but I interpret it as follows:
Turning the knob works like it would in a normal racecar, and moves the brake balance front or rear. However, given that you need to make small balance changes around the lap for high- or low-speed entry, having to rotate the knob around is a pain in the ass. Particularly hard to get it back exactly where you started. The lever makes tiny adjustments based on the 'global' balance (set by the knob), you can throw the lever forward or back.
So for example, center position - global setting (from knob).
Forward position - Global setting + 1% front
Rear position - Global settign + 1% rear.
