It's titled "A Tour of the Original Android Demo"
It'd be like asking a solider in 1915 what war they were fighting and they respond "WW1" (as if they new in advance that there would be a second world-war 30 years later).
In fact, when I was using the demo it felt like the color flip phone I used to have around the mid 2000s, and in retrospect it's hard to tell why Android became what it did today. There wasn't much unique "smartphone" functionality in that demo from today's perspective, although I didn't see the original materials about how it was positioned.
