Объяснение:

Возвратное местоимение используется для того, чтобы не повторять существительные, стоящие с притяжательным местоимением.

Например: Is this your pen? ( нельзя второй раз говорить Yes, it is my pen), а правильно : Yes, it's mine.

Is this your book? Yes, it's mine. NO, it's not mine.

Или еще пример: Это книга Ербола. Да это его. Is this Yerbol's book? Yes, it's his.
