Why do youtube readers mention astrological signs in their readings?

Really, they are pulling lots of cards. In many readings you will get cards from all minor arcana, so what is even the point of mentioning the astrological sign? If you only did a 3 card reading maybe that would make sense to mention them because it would help people decide if they picked the right reading. I remember watching a reading and that lady mentioned every single astrological sign because she got cards from all minor arcana categories.
