It doesn't mean it wasn't hit with a procal. If tire size, or low pressure monitoring trip level changed a procal would have been used. Great tool, but if a mistake is made, you can enter some ridiculous things. When I first did it to adjust tire size, I deleted the diff ratio on accident. My Jeep had shifting issues, as well as no working speedometer, and accrued no mileage until I figured it out for 5 miles.
Of course, the dealer would likely have flashed the memory in some way to clear that first thing.
