for the average joe, 'twin turbo' sounds better than 'turbo'.
how many people do you know that would drive a more laggy vs less laggy car, and say the more laggy car is more sporty...
hardly anyone spends any time over 6000 rpm. And the car isn't marketed towards the serious performance crowd (more like the 'ooh, sporty sounds nice!' crowd).
