As 'scrolljacking' goes, this is excellent, I actually really like the design - showing multiple angles/layers without taking up so much vertical space with multiple images, since it changes (instead of moving) as you scroll.
That is because it does not actually take control away from you with any sticky/magnetic spots. A lot of scrolljack presentations have a really laggy pagination that is somehow about as precise as fast rewinding your DVR was back in 2011.
Yes, that's a sure way to make it bad. I don't think it's given (as a sibling comment to yours suggests) that simply not doing that is sufficient for any other scroll manipulation being fine though.
The intention's always good, I think, it just rarely is as nice as the author felt it would be.
big difference between scrolljacking and just using the scroll position for something. This is a legit good use of it, because the actual scroll behaves exactly the same as any other page.
