I have not red the original article so maybe I am mistaken, but the post submitted here seems to suggest that there was one group only not two groups. There was one group and they retyped only half or so of the words and not the other half and were found to remember the retyped words better.
I do not know if that makes a difference, but I think it might and could. The retyped words might have whatever quality or for whatever reason might have been easier to rememmber than the non retyped words.
Unless in the original article it suggests that the experiement was carried out in the way you suggest, I do not think there was much control of variables.
