In his course, at one point he says "women like when you tell them what you want, how you feel about them." then he contradicts himself by saying "create uncertainty, she must not know how you feel about her, otherwise she will realize she already has you, there is no challenge"
Quite frankly it's all about him selling this course for $$$. If you like a girl, and she acts like she is interested in you, ask her out, if she says yes, good, if she says no, move on find another girl. If a girl likes you, she will give you access to her life, it's simple.
