If you want to partition (shard) your data, then this will work roughly the same in MySQL and Redis. But this article is only about partition tolerance. Neither MySQL nor Redis are inherently distributed, so it's not possible to generally state that either is partition-tolerant or not. The article is misleading here. You could use a replication strategy that is partition-tolerant or you could use a strategy that's not partition-tolerant.
