The 'horoscope of Leo' has nothing to do with astrology. Horoscope is from greek "time watcher", most likely meaning guardian. And it is the snapshot of celestial bodies against the ecliptic at this time or that. And if you follow the rules about reading them, they aren't vague. :->
But yeah, mostly what is described in the article is correct. The main purpose of divination is to make you think. Too bad that for a lot of people consulting a diviner is an excuse to continue not thinking.
