The system may be acting in the opposite that you prescribe. It appears to use a smaller turbo with minimal lag and lower peak output that is in operational boost levels at modest amounts of power, and the electric super charger is kicking in with large right foot applications.
Sense the turbo is far more energy efficient than the electric, this results in keeping the energy efficient gains of the turbine, but with additional horsepower at will from the electric super charger.

LOL, i forgot it's audi, the maker of the inline 5 cylinder
