As I understood it, the body of the Quincy automatically rejected the Bankai when it became Hollowfied, to prevent them from being injured by the "poisonous" Hollow reiatsu. I'm not sure if it was Hollow reiatsu, but I recall that.

I guess what Quilge did was to basically absorb the reishi Ayon's body was made of, which did not include his reiatsu, and that way increased his power without getting in touch with his reiatsu.
