No, he means understeer, although not necessarily for the reason he claims.
When you get at least 50% of torque to the rear axle it's a piece o cace to rotate the car once you will have turned ESP off.

So yes I meant understeer in the drivetrain layout context.
Power application can certainly induce Under/Over, but since its observable even when the throttle is neutral, weight distribution plays a large part as well. The Q7's is front-biased 52%-48%, which will induce more understeer plowing.
A perfect example of this can be found in Miata V8 conversions. Despite already having a suspension designed for a car having an almost precisely 50-50 weight distribution, you can still easily accomodate the 53-47 distribution that results after you drop an Chevrolet LS aluminum V8 into it. It's simply a matter of adding a little more roll stiffness to the rear end.
Yes: as a car's weight bias departs more from 50-50, then the tradeoffs to create neutral handling get larger, but when you're relatively close to 50-50, it's just not a big deal.
