Never once do they say the jutsu has to be undone before the user can rescind the contract

Thats just a fan assumption

Madara simply says if the reincarnated soul knows the hand seals, they can sever the summoner's contract with them he never once says the summoner has to release the jutsu, Madara describes that as "the one risk of the technique" this means that if the person knows the hand seals they can do this any time they choose unless the summoner has already bound there consciousness with the paper tag
