Why do people drink stuff straight after a workout though ? Cos they feel a bit shit and they feel better for having some carbs and protein. I think what Dave Barr was saying was there isn't necessarily a protein carb window right after a workout where you suck up extra amounts of carbs and protein and your brain controls insulin sensitivity with extra Intel processors to make maximum use of nutrients.
It was popular to state the value of post workout meals both recently and in the past, particularly when selling some formula like a meal replacement with extra calories supposedly optimised for this time.
One thing I do agree with in that article is eating at night. Nutritionally alongside actually eating enough/properly during the day, having some food at night, like if you get up to take a piss, is a very good idea, even if you did stuff your face before bed.
