I've thought more about this looking at the end of the runway business (and actually taken notice of what I do when landing). I think transferring your central vision to the far end of the runway is more useful for student pilots, but as you gain experience you are able to look more directly at your aim point and use your peripheral vision to take in the horizon and runway perspective. This is definitely true for chopper pilots - start by looking at the horizon, then, as you gain experience, look at the spot and use your peripheral to gauge the horizon. I guess the main thing is that you are getting all the visual information to your brain in a way it can be processed and used to good effect, and yes, there will be various different ways of doing that. I actually tend to 'scan' between the touchdown zone and runway end. It is interesting to break down into its parts a maneuver that we stopped thinking about long ago and just 'do'.
