That's close to what I said; the chassis (sprung mass) rolls during cornering because lateral acceleration generates a force acting on the CG of the chassis, and the "pivot point" of the chassis is is below the CG. The chassis is not actually rolling about the contact patches of the tires, it's rolling about the suspension-defined roll axis (the "pivot point"), which is typically somewhere above ground and below the CG height.
