Thanks for pointing that out! This video doesn't seem to be available in the US, so you can also see it in the slow motion footage here, right on the finish line:

(You can see it in normal speed too, but I can feel the formation of shapes better in the slow-mo, instead of it just feeling like blinking)

Ha, and that video isn't visible outside the US!

I guess pick one or the other depending on your country (or if neither works, search for one that does).
