Yamashita san, Go version in AlphaZero 2017 finished the training in 34 hours according to Table S3. And it looks like AlphaZero Symmetries in AlphaZero 2018 finished the training in the same time according to Figure S1. So I think that the authors had adopted AlphaZero Symmetries in 2017 paper by mistake and retried the experiment again in 2018 paper. In order to compensate symmetries with real self-plays, they generated 8 times more games and reduced positions per game to 1/8. It is just my guess^^ - ICHIKAWA Yuji
