Is he blocking me from getting another job?

I am in limbo right now working for 2 depts. My current position is being phased out and another dept is taking me on in the same title. Lateral move... anyway... My mgr was supposed to tell me all about this months ago. What he told me was that my position was being phased out and there was little to no interest from the other dept on retaining me. I was understandable surprised when the manager of the other dept contacted me to begin meeting with me to discuss the transfer and an email went out giving my transfer date of 90 days from now. Yesterday my mgr told me not to pay attention to that email, it's not correct. This morning he told me that no one was supposed to contact me about the position and the date is wrong nothing is set in stone and I am still being phased out. WTF? What does that even mean? Can he fire me? He has expressed interest in the position himself. He took cles even. Could he be blocking the transfer? If this has already been told to me, who at this point do I not listen to? The VP of my dept confirmed I am transferring so what is my mgr trying to do?
