Thats was an innacurate speed when it loaded. Since the video had previously loaded over EDGE, it stayed on your browsing history, and so when you streamed it over Wi-Fi it didn't take long because it was already loaded and played to begin with.
You can't see it very well in the video, (a web video of a web video doesn't usually look that great,) but what Eric is trying to explain in the audio at that part is when you stream YouTube over Wi-Fi, it senses the faster connection and streams a MUCH higher-quality video. It's less compressed and higher resolution. It's a very clear difference in person. The only difference you can see clearly in a video is that it starts much faster, but that is the connection, not a cache.
The lower-quality stream, if it were cached (and I'm not it would be, since this isn't a browser) wouldn't help with a different, higher-quality stream.
