Interesting. I expected that this effect took two eyes to see, and I lost the use of one eye a few years back. When I saw your comment before reading the article (shame on me), I assumed that I wouldn't be able to detect any motion a 'normal' person could. Surprise! I could! Also - it doesn't take much to make it 'stop' (I assume I'm arresting saccades to do so), but I don't really know what I am doing. What did you do to learn how to prevent your eyes from doing that? I can make it go and I can make it stop - but I am not able to tell you what I am doing to do so...
