It’s the same as with Hermione’s body and the unicorns. They are stones as long as they are Transfigured. When Transfiguration stops, they will soon suffer. That’s why Harry kept Hermione’s body and now thinks about sustaining the Transfiguration of Voldemort all the time—he wants them to stay Transfigured until their state can be helped. He’s kind of frozen now.
