The roll axis on an airplane (and boat, and roller coaster for that matter) is used to replace lateral G forces (what slings you side to side and causes cars to skid out) with Positive G forces (getting pressed down into your seat). The pilot rolls the plane (or the track rolls the roller coaster) to an angle where your body is standing or sitting vertically on the curve, not perpendicular to it.
