I agree that it does work. My W started the DB discussion by listing a lot of the things I had criticized her for in our M. She said I was right on all of this after all. She was a bad person in this M hence she needed to leave me and find her true self. I was definitely taken by surprise, not only by the desire to leave, but by the complete change in the structure of our arguments.
WW had an OM (EA) waiting in the wings, so I can't quite say whether she was honest about her self-assessment, but I simply point out that the way she approached it was unsettling. I remember thinking of it a "emotional jujitsu" too.
I also think it's part of DB and it's called validation.
