That seems like a very long-winded way of saying he didn't love himself, so he worked to reframe and reinforce positive memories and loving himself. That's pretty standard in metta meditation, you are instructed to direct love and kindness towards yourself.
I think it is not quite that simple. The key insight isn't realizing that you don't love yourself, or whatever, but realizing that your behavior today is seated in specific reinforcing memories from your past, which can be specifically re-framed in a way that causes the present behavior to dissipate, as if by magic. Assuming that is really the mechanism for what's happening, I don't see a reason to think, a priori, that just 'loving oneself' is sufficient, as it wouldn't exercise that exact mechanism for self-transformation. Anyway, my particular case did not involve anything to do with loving myself, but the same machinery seemed to work for a very different neurotic behavior.
