the heart = feelings of bond between nakamas IMO Ulquiorra was so intrigue with Orihime's heart for her nakamas effort in saving her so that was why when he finally died away & turn to ashes he finally understood what this hearts represent ... maybe this two chapters was the only instances when Kubo Tite displays his concept of heart and or nakama's bond (nakama = more than just a friend or partner & or sworn brothers & sisters)
