No it just means you made good progress. I guess it depends what kind of therapy you are doing. For me, real therapy began once I felt comfortable enough to open up and talk with her. I am sure it depends on where you are at in the process. If you are in talk therapy and you were not able to speak with him much and open up, it makes the process a little difficult. Either way he did not mean it as a threat. It sounds like he was complimenting your progress. I would talk with him so you are not concerned that he is going to terminate early.
