Here's the news article:
Special Ops Training
Like the ARC-170, the Special Forces TIE fighter features a primary weapon with an attack value of "2," plus a zero-cost, non-unique Title upgrade that allows you to boost that primary weapon's attack value to "3" or gain a secondary benefit. However, where the ARC-170's Alliance Overhaul Title offers you the ability to improve the accuracy of any shots you fire from the fighter's auxiliary firing arc, the Special Ops Training Title for the Special Forces TIE fighter is less about choosing the arc from which you want to fire and more about rewarding you for firing from both.

It seems pretty clear that you either boost a primary arc attack or gain an additional attack from the auxiliary arc and that allows you to attack from BOTH arcs. No where does it mention making two auxiliary arc attacks.
