sigh Why me...

Firstly, Ulquoirra died from cero wounds. Thus he most certainly was not "cleansed". Secondly, Ulquoirra being a high level Espada was an arrancar born of a menos. Menos are born from hundreds, if not thousands, of hollows and then consume hundreds, upon thousands of hollows. As such, the most likely scenario is that dead menos level Arrancar -> multiple souls are returned to the circle of life and death. I.e. the identity that was the "arrancar" is lost, wither partially or entirely we do not know. Just as we do not know if the identity of the menos is born during the menos creation process of if a dominant hollow "carries" their whole identity in-tact through the menos creation process.
