I would think that she would gain any benefits that are applicable to her.  For instance, if she's tapping on you for a cigarette addiction but doesn't smoke herself, she would be even less likely to take up smoking or to have a problem with any other addictive behavior in her life. 

Good question, by the way.  Ask your therapist the same question- I'd be fascinated to hear what she has to say. 

Namaste.
