   On new work, its probably because the rest of the wall also didn't have enough paint so when you touched up one area that now had more paint then all the surrounding. The touched up part has two coats whereas the rest of the wall has only one coat. The solution is to always two coat any surface. Sometimes you might have to three coat.

   Another trick is to roll the paint out very dry from the touchup outward.

   After doing the basic fix, start from the touchup with a roller with very little paint on it and roll outward in all directions.  Eliminates the "wet edge".

   This also happens if you used paint/primer combo paint (behr from homedepot for me) over the regular paint.  I painted that wall 4 times, finally using just regular paint.
