I think there's enough vagueries with the different scanlations out there of Bleach (M7's versus Sleepyfan's), that we can pretty much hold what was said in this chapter to be up to interpretation. After all, lots of different people have different ways of translating the Japanese. And still, even with a proper translation, Kubo's intent might still be hidden.

I think it would be so wonderful and magical and dramatic if Kubo brought him back even at the end of the story, at the very last battle -- because suppose with a heart, Ulquiorra is more powerful than even Ichi-beast? He would maybe turn the tide against someone like Aizen.
