As shown by the Dead Demon Consuming Seal, the Shinigami would only seal her if she used his chakra to seal someone's soul away, so she doesn't die. She does however, loose chakra the more she uses it and the longer she's in the cloak, the more pieces of her soul he will want to consume since she is using his power so that's why she doesn't die
