Yes, it is more secure.
1) theory: Unlike traditional thread on + lockring one, ISO 6 bolt interface is NOT being fastened in the direction of applied torque so the bolts have only shearing load on them.
2) practice: disc brakes were designed for exerting much higher torques than any rider ever will.
