Except that we know for a fact that he didn't because Oro already reanimated
someone that knew how to use the jutsu.
I guess Oro is lucky he never had to release the jutsu before the 2nd was sealed away, or else the same thing would probably have happened with him as is happening with Madara.
Does he though? So far, the only person we've ever seen do that was the person who reanimated them in the first place. Will that technique even work for someone besides the jutsu caster? And if not, then it wouldn't work on Madara.
