1. Note that the spectator and annihilation decays correspond (at the quark level) to different two and four quark states. The amplitudes for annihilation and direct Q decay interfere in specific (hadronic) decay channels, but not in the inclusive rates. Hence one adds the two contributions in the total decay rate.
