It's just an input right? Forget your expectation that an input causes a 'page' to move vertically; the screen is just a canvas that can change over time or in response to inputs.
(But, because it breaks your expectation is why people don't like it, call it 'scrolljacking' i.e. hijacking scroll behaviour, etc. It's worst IMO when it's done to make the page 'sticky' at certain banner points, so it takes unintuitively more or less scroll movement at certain points as you move down the page.)
