Actually I think they'd rather call this a bug - even if it was some test. Which is not unlikely. Together with "Instant" it could very well be that somebody at Google had the idea to only display a fraction of the results and force the user to refine the search query, getting new results while he is typing.
But since the recent emberassing display of background images they had to kill of the day the came out because user where complaining they would probably rather admit a bug than another "feature" gone wrong.
