I think a better way for the article to state that would be that, above 10 mph (or whatever speed they claim), rolling resistance is not longer the predominant factor. I wouldn't say that it's no longer a factor...as it will continue to be a drag on your speed, and probably with an increasing amount as your speed increases. Rolling resistance's increase is linear, though -- wind resistance increases with the square of speed, so its influence ramps up much faster as speed rises.
