You may want to refer to that as "dual-touch" since it can only register a 2nd point and the movement based on these two points. The "multi-touch" patent is much more sophisticated by using and following more than two points at one time.
Experiment: • Place your left index finger on a MB or MBP trackpad and the use your other index finger to scroll. You get the same effect as scrolling with two fingers. • Place two fingers together on the trackpad and try spreading them apart in opposite direction, like you would do with an image of webpage on the iPhone. It doesn't work; in fact, it cancels out the other movement.
