Aizen knew Rukia would stop Byakuya from killing Ichigo. Ichigo looks like Kaien Shiba, and Aizen most probably knew about Rukia's deep feelings for Kaien, considering he was responsible for his Kaien's death.
If Ichigo was that important Aizen wouldn't have taken a risk that big. Ichigo should have just died from the attack itself and not from needing a killing blow.
Anyway its pretty easy to see that Aizen rigging all of Ichigo's fights was thought up on the spot and really doesn't even matter to the story. It's just one of those things Kubo put out there to salvage bleach for a little bit longer.
