When you start an original XBox game on the 360, the 360 checks if there's a new version/whitelist for the emulator. The update you experienced was either an emulator update or whitelist update for the emulator.
Original XBox games have no way of being patched by the 360's updater, they have their update checkers built into the game and updates executed via an update.xbe file. Of course, with LIVE access down for original XBox games, this is now impossible.
