I've read this somewhere before in a book. It was actually recommended halfway in the charged section between the IC and the TB. This was the explanation, at least the geist of what I understood.

When the throttle body is positioned closed, the charged air will tend to flow backwards toward the turbo. The idea is to relieve that pressure before it reaches the compressor. The intercooler is already acting as an expansion tank, therefore there is really no need for it be relieved off. Since the charged pipe could increase the velocity of air flowing back to the IC (then to the compressor), it is recommended that this area be relieved from pressure.

It kind of makes sense to me tho.....Peace
