This will allow more amino acids to skirt past your enterocytes and liver and make it into the blood stream where they are taken up by skeletal muscle. Then take your carbs one hour later, which still allows you to take advantage of the metabolic "window" post workout.
Of course I wrote this.

Before you all get your knee wraps in a knot, I'll explain. The macronutrient composition of a protein meal effects where that protein is ultimately deposited and incorporated into new proteins. This is due mainly to the effects of insulin on amino acid uptake in tissues that will either deaminate and/or retain that protein well before your muscles ever see it. Such tissues include the gastrointestinal tract (stomach, small and large intestines, and the splanchnic bed (liver), then into the periphery which include ALL organs and tissues of the body, not just muscle tissue.
It turns out the insulin causes fewer amino acids to make it past these first pass organs/tissues. Why? Because as I said, those tissues will take up a greater percentage of those amino acids and use them for their own purposes or deaminate them.
A model based on the collected tracer data demonstrates the effects of carbs on the partitioning of ingested proteins. (note the difference between fast and slow proteins as well)
Milk protein
Splanchnic proteins 18%
Peripheral proteins 34%
Sucrose and milk protein
Splanchnic proteins 35%
Peripheral proteins 26%
Sucrose and soy protein
Splanchnic proteins 37%
Peripheral proteins 19%
So, this data/research is what my comments were based on. Of course the absolute amount of protein ingested can make these facts less important. You can simply overwhelm the system with quantity and get more amino acids out to the muscle tissue. But as far as my earlier comments are concerned, I stand by them as accurate.
Here are a few papers that illustrate these points further.
