That is certainly what it sounds like but it also speaks volumes to the guy that did the touch up. When your eye (and I expect you have a critical one) can't see the repair and two different processes were used, he did well.
I have seen a situation where a known repair was done but it was repaired using a base coat/top coat process. When polished the color of the paint was on the pad. As best as I could figure was than when the car was sprayed/blended the base coat fogged a larger area than the clear coat that was put on top of it. It was kind of dirty when I worked on it and I didn't see anything particularly unusual but I spent a great deal of time trying to figure out what might have happed. It actually would shed paint around the area that had been prepared. I did the vehicle again several months later and the problem was not present. I could only attribute it to over spray that was not covered with clear.
