The process has changed. You are no longer interviewed by your original ALO. Once you are almost complete with your application, your ALO will change to an out of state ALO that you have not had prior contact with. This is the person that will do your interview. Since the OP is so far along in his application, the ALO listed on his portal now may indeed be the one that will conduct the interview. If you have no questions, there is no reason to contact ALO just to contact them, but it wouldn't hurt to contact him or her and ask about the interview, they will tell you if they are the one that will conduct it or not. As MikeLaw84 mentioned, it never hurts to reach out. If you don't reach out, the interviewing ALO will contact you to set up an interview once your application is complete.
