I think that was a recent development for him. After joining the Gaang he threw away the pent up anger, he also no longer needed to prove himself to his father, so as far as he was concerned, their sibling rivalry was over.

I like to think that by communicating with Katara and Sokka, he got a better insight of sibling releationship and realized that you stick with your brother/sister, through good and ill. I think he wants to build this kind of bond with Azula. Sending her to heal was a good first step.
