He means that you should NEVER chain actions. This is an ongoing debate that usually results in everyone giving room for exceptional cases. Personally, I have never chained actions and have found no need too. I use more "standard" ways to accomplish processing chains in the biz logic. But, there are those out there that do find need for it. Until I am in there shoes I'll say, "To each his own".
