I am not sure why do you expect to see a difference. As long as they are sufficiently separable, then they would have a similar performance, given that they are being operated with the same CQI.
I suggest to start with only a single BS with two users, disable the uplink, and just look at the downlink performance. Set the K factor high (20 or something), so it is mainly LOS dominated. Fix the angleMeanZOA to 45, angleSigmaAOA and angleSigmaZOA to 0, and then change the AOA angles of the two users and see what happens. For similar AOA angles, you should see a substantial performance drop, compared to the case where they are sufficiently separated.
