It's easy to conceive of a device which, for whatever reason, gives an "absolute" reading accurate ±2°C, but which tracks temperature changes somewhat more accurately. And hence a small difference between successive readings still has significance. A real-world example is a mercury thermometer in which the glass has been physically shifted relative to an adjacent scale. So 18°C reads as 20°C, etc.
Cheers,
