Edit: Also, he says "Where is that museum with Egyptian stuff in San Jose?" and after he closes it, it shows "where is the tallest building in the world"
Disclaimer: the only edits I made were to cut time between each of my queries, as well as re-order some of the demos from the original order I recorded them in, so they would fit into categories. None of the queries themselves have been edited or cut down, and the sequences are intact. The processing time happened exactly as you see. This demo is made on the early build of Android 4.1 (JRN84D, takju build for Galaxy Nexus I/O edition), on a wifi connection. Consider this beta.
So what you're seeing are places where the queries were reordered.
That could explain why some of the results have other things shown when he closes them.
