Good point. It's one of those holes Kubo leaves in the story due to writing on the fly.

I could come up with some points to justify it but I'm just speculating and these are in no way true or sourced: 1. He stole it. He was just a lieutenant and probably wasn't allowed into such an area. So, he impersonated a Captain. 2. KS. This could also apply to point 1. 3. The flashback was after he was made a Captain. Looking at it, the Aizen speaking is the flashback Aizen, not Butterflyzen. So, after having created the Hogyoku and then becoming Captain, he could be saying that.

Okay, that ^ was COMPLETE rubbish but at least it's out of my head.
