Not understanding VAOC calibration

I found this video on the discord https://www.youtube.com/watch?v=_ooNQt7qPSs that goes through vaoc, but I feel it doesn't help my situation. I calibrate t0, change camera settings, make circles align with nozzle, then move onto t1 and do the same. I go back to t0, and it is "misaligned". I fix it then go back to t1, and it is misaligned. From what I understand from that video, switching should save the calibrated toolhead, but I don't know what I am doing wrong. The pics I added are t0 > t1 > t0 round 2 > t1 round 2 > t0 round 3.
