If i had a guess, the wannabe kenpachi has to kill the old one like you said, i'd go ahead and assume there was no one better than her for the title. As in, no shinigami could best her in a battle, so she could not be succeeding, and probably resigned, had a change of heart and went to the 4th division to heal others, when apparently in the past it seemed she caused nothing but pain. Born again christian perhaps?
