That's the poor man's supercharger, with the added bonus of hot, oily crankcase vapors. No better place for it then directly down the throat of the carb.
Kidding aside, lots of bikes, KTM's real dirt bikes w/ FCR carbs, for example, have their crankcase vent hoses attatched directly to the carb manifold. It works fine. In the case of the CPR set up shown in the picture, my preference was a bit of a cleaner less homemade look, so I just left it outside.
