This special tension wrench is supposed to provide torque for only the inner cylinder which opens the lock, but how does this help bipass/set the second shear line?
You're only setting 1 shear line, actually. It just matters which one you set, and you cannot mix and match shear lines like you can in a masterkeyed system.
Here's a key:
[] - Driver
|| - Master Wafer
\/ - Key Pin
Normal Lock:
[][][][][]

Pretty obvious shear line!
Mastered:
[][][][][]

\/\/ \/
Several possible shear lines!
SFIC:
[][][][][]
||||||||||
\/\/\/\/\/
Several possible shear lines! (BUT WAIT!) it's actually only 2, distinct, shear lines, both of which perform different functions. There is a small sleeve:
So, you're not actually setting TWO shear lines, you're setting 1 of 2, and if you use the special tool? You only put pressure on that sleeve I was talking about, that sleeve, when it moves, pulls itself INTO the body of the plug, and then you can remove the whole shebang from the housing of the lock.
