I noticed the same thing recently. When I started uploading I was thinking along the lines of "if my comic were an animated series, each chapter would be an episode's worth of content" but then I realised readers wouldn't be notified of updates, and there'd be no way to leave a note with each page. I think I just misinterpreted the wording... =u=;
Now that I've understood the concept, I like each page being an episode. Having thumbnails for each page is good, and I also like that you get to choose the thumbnail for sharing too. C:
