I checked and I could not find anything in that thread to support your conclusion. AFAIK, and based on my experience, A2 uSD cards do not perform worse than A1 on RasPi3, however they cost more and do not perform better.(except the pi 5 with a beta firmware, which means A2 actually perform worse on the pi 3 than A1!
