The Left Angle Cross of Prevention, in this ordering, is named for Gate 10 and Gate 15 rather than Gate 15 and Gate 10, the same four gates as its mirror cross with the personality and design roles exchanged. Its first article reads that exchange as self-conduct now answering to a correcting instinct. What it does not trace is where the four gates sit on the wheel itself, the Human Design mandala's division of its sixty four gates into four Quarters, and by that measure this ordering draws on exactly the same four Quarters as its mirror, one gate from each.
Gate 10, the personality gate here, falls in the Quarter of Mutation, purpose fulfilled through transformation. Gate 15, its personality partner, falls in the Quarter of Civilization, purpose fulfilled through form. Behind them, Gate 18 falls in the Quarter of Duality, purpose fulfilled through bonding, and Gate 17 falls in the Quarter of Initiation, purpose fulfilled through mind.
So the self-regard and tolerance the first article reads on this ordering's surface still draw on the arcs of transformation and form, while the corrective instinct and the formed opinion beneath them still draw on the arcs of bonding and mind, the same four arcs its mirror cross draws on with personality and design simply reversed. Reversing which gate carries the Sun changes what the cross is read to serve, but it changes nothing about which Quarters supply its four gates.
