I believe those gestures were all first patented for the notebook computers when Apple placed a trackpad by shifting the keyboard up next to the screen. They shortly (after the patent was given) assigned these gestures to the electrostatic pad a few at a time to control movement on the screen. one finger, two, three, four, tap once or twice or three times, fingers and tapping, and finally, pinch and spread with two or more fingers.
as your afterthought noted, Apple laptops' keyboards were "shifted" from the start, because they used trackballs before trackpads; but it was 2005 (11 years after Apple's first laptop with a trackpad) before Apple purchased the technology that put "multi-touch" gestures into their trackpad and iPhone
(got the dates from wikipedia, but i worked with every generation of Apple laptop and recall Apple's multi-touch announcement and how the new gestures didn't work on older trackpads)
