There are a few similar approaches out there, which perhaps go even further towards allowing change to happen (or not happen) through self awareness. I especially like hakomi therapy which takes a fundamental stance that the therapist should first of all support the person in being exactly who he or she is in this moment. I also very much like "The Work" of Byron Katie, an extremely simple technique for becoming more aware of my expectations of how people should be which helps me become more accepting of how they actually are. I've no idea whether these approaches are useful or appropriate for Asperger's but I like how they treat the 'current state' with respect rather than as a pathology.
