Как я поняла, защита, созданная материнской любовью (Лили), и то, о чём говорит Дамблдор, - это разные защиты. Или нет.

«The magic I evoked fifteen years ago means that Harry has powerful protection while he can still call this house ‘home.’ However miserable he has been here, however unwelcome, however badly treated, you have at least, grudgingly, allowed him houseroom. This magic will cease to operate the moment that Harry turns seventeen; in other words, at the moment he becomes a man. I ask only this: that you allow Harry to return, once more, to this house, before his seventeenth birthday, which will ensure that the protection continues until that time».
