I think that's correct. What I think the car does is, when oil is changed, the tech fills, verifies and then "sets" the oil level, or the resetting of the service interval does that last part. So the car is watching not only the level to be normal, but also monitoring for any significant increase or decrease from the level the oil was at when it was last filled, i.e. it's monitoring for oil loss or contamination.
If your oil level was last filled to 48mm and now it's 38mm that may trigger a message, even though it's within the "normal" range the loss of that oil is not normal. I don't know if there is...but finding the data field of that "stored" oil fill level would be nice and give us some basis of checking the status ourselves.
