Fair point, simply put thread lock can't stop a freely rotating bolt screw out of a nut of some description if the threads are all ok.
When installing a BB, clean both the threads in the frame and the BB. Face the BB shell if required and chase the threads. Grease the threads. Put the non-drive cup in half way as a guide, screw in the drive side and torque up as specced, then tighten the non-drive up. Should be fine.
