No, the large turbo feeds the inlet of the smaller turbo. The smaller turbo spools up fast and gives you boost, as the larger turbo spools the pressure ratio across the smaller turbine goes 1:1. The turbine is no longer doing any work to the air coming in so it doesn't heat it up or decrease the mass flow rate
