absolutely not true.. if the clutches are working, then BOTH wheels get the SAME power, thus the dry pavement wheel will power you out.
IF the clutches start slipping, then its like an open diff, and the least traction tire will spin.. sometimes as you mention, helping the clutches grab (applying the brake) again will enable the LSD to work again.
once the clutches are worn (eventually), then nothing will help except repair.
I got my 2wd dually stuck in my back lot last year.. very heavy clay mud.. all four tires spun together.. so lack of traction on BOTH wheels also doesn't help. a locker would not have helped here.. only 4wd
