It worked for me sewhat after I understood the interaction and was somehow nice UX (I agree that there is better option for immediately better usability) However, I think even considering UX, there are clearly interaction hints missing to encourage the scrolling interaction in the first place. Secondly, it makes it really hard to find information again after reading it once sequentially. A menu type thing would probably fix that as well.
