I read somewhere that it's sort of like a 'knight in shining armor' philosophy. OP needs "rescuing" and the WAS thinks they're the person for the job. OP is someone who needs help. They help the LBS feel empowered and needed. The OP makes LBS feel better about themselves.
I've read this as well (can't recall where) and believe it myself.
Getting over a painful experience is much like crossing monkey bars. You have to let go at some point in order to move forward. ~ Joseph Campbell
