The code above works on everything but the last page of my borderless scrolling page, any reason why?

Question

I used the code above to limit the animations to one play and so they remain on the page after playing, however, the last set of animations do not all remain visible when scrolling back up the page, is there anything I should add to fix just the last set of animations?
