A similar movement of the ailerons (or more specifically a similar roll demand) on the 737 requires a much bigger input of roll on the yoke. There is also a larger dead band on the 737 which has to be overcome. The 777 also has a much larger momentum, which means that it isn’t disturbed by gusts as much (even though you can sense them). If you handle the yoke in a similar way to a 737 on the approach you will just end up waggling the wings a lot, like in the video. As you then counter the ‘waggle’ with an opposite large roll input you’ll just end up in PIO.
