My understanding is, due to auto release semantics, your object might be auto released again during current pool draining. So it will be put into outer Autorelease Pool, that's to say the dealloc are not guaranteed to be executed at specific timing. ARC still relies on retain/release/autorelease, so it has the same behavior.If your code must unregister notification before something else. It's better to find a more deterministic timing.
