There is no problem with using positions 1 and 2. It will not go into 3 if adjusted correctly and strain the shifter.
No danger of slack because setting it up you click the lever once before the cable is installed. That plus the low stop not allowing the front mech to go further in precludes cable slack; you can click the last release click does but it does nothing but click. Anyway, just another way to approach the task and most importantly, it shows that a 3x shifter will absolutely work with a 2x crankset.
