(Perhaps, it used to be true for ISAM tables.  The documentation should be

You are misinterpreting the statement; it says that the database will be safe after the SQL command returns (all SQL commands active on the table, for that matter). That is to say, if the power were turned off while any (update / etc.) SQL command was running, you could expect corruption.

Again, make sure you check how your OS deals with write caching and consider turning it off on the partition / disk you're using for DB storage.
