Maybe in your upcoming phone sessions, you could ask your T but frame it in an analytical way? For example, "Right now, it's very important to me that I understand if you will miss me as a person and not just the qualities that make me a good patient/client". That way you kind of get your answer no matter what. Best case scenario, your T is upfront and says "yes, I will miss you as a person" worst case scenario you can try to understand what the answer is from the overall conversation that follows from asking the question.

Without knowing your T or the relationship you two have, it sounds like he or she might be guarding himself/herself from becoming too attached. This has benefit to you and to the T. If your T shows that he/she will miss you, perhaps you would feel obligated to stay? If T becomes too close to you, it's hard for them (or so I've heard) to do their jobs effectively. Either way, I wish you the absolute best.
