1) My post earlier was directed at the comment by Godisme

2) From what I understand, Aizen's incomplete Hogyoku either needed to feed off of the spiritual power of other beings to work, or this was Aizen's way of trying to complete it. Meanwhile, Urahara's Hogyoku wasn't complete either, but didn't need to devour spiritual power in order to work.  When Aizen combined the two, it created one complete Hogyoku that operated like the one Urahara created.  Does that make sense?
