The turbo is compressing the air by reducing the volume a certain amount of air occupies.. The supercharger will further compress the air by reducing volume the same amount of air occupies. The blower will provide a pressure increase to whatever air is available. If anything, the turbo will be a restriction, letting less air enter the blower. This is kind of a wacky setup, the twincharged setups I've seen were pretty much the opposite of this one in that the supercharger comes first and has a control valve "in series" to ensure that one compressor isn't choking the other.
