The Chexit feature blocks the centercase from moving, thus the cam on the back of the centercase will not rotate when the CX feature is armed.
If they had a mechanical 360L, and tried to turn the mechanically unlocked lever while the Chexit feature is armed, the cam would still be locked and they might be able to generate enough force on the lever to twist the tailpiece of the trim going into the cam on the back of the device.
