from looking at the chapter again, it seem that there was a deliberate attempt to get the hogyoku from aizen. Yoruichi's boot seemed to be daggered to a point and the place where she struck was the exact place aizen implanted the hogyoku..... maybe that is theyre plan, get rid of the hogyoku at all costs and leave shinigami aizen to ichigo
