The answer:  they are at the same place at "step" (time) 3.33, but if you step
through the applet, times are discrete--you see only step 3 followed by step
4.  It's like you're using a camera with a fast shutter speed, where the action
takes place between clicks of the shutter.  It's late at night right now, and I
can't think of the term from psychology that describes how the brain processes
visual images--it takes discrete impressions from the optical nerve, and runs
a continuous movie.  That's what's happening with the applet--leads to a nice
discussion of science (or film-making).
