Because it knew at that time that whatever is wrong was WRONG. I don't know how many on/off cycles it takes to clear the code, but it should have set a hard code when the light came on. When the check engine lamp is off, the computer is believing whatever sensor is making it do that. Pretty much the only sensor that can let it go that far out of whack is the o2 sensor. If any other sensor was that far out of spec, like the airflow, manifold pressure or throttle position sensor, the the O2 sensor would say "hey, I'm swimming in gasoline down here" and you'd set a light for the O2 sensor reading too rich. I expect your code will be for "O2 sensor stuck lean". I can't remember if a high resistance connection in the circuit would make it read lean or rich, but the wiring is always a possibility, but I think it's more likely to be the oxygen sensor itself.
