You're right, those wouldn't be updated. I know you can make a working user by inserting those rows, but I don't know that all the statistics would be correct. But the user statistics are updated in includes/functions_databuild.php, in function build_user_statistics(). It calls build_datastore() which is in includes/functions.php. It just updates the row in the datastore table, unless you have a different datastore cache configured in the config.php, then it needs to call the function to update that as well. If you don't have a cache defined then you're good just doing the update that you see in build_datastore().
