In the spirit of the original article I think point is not whether it was too much or not enough abstraction--it was the wrong abstraction. His abstraction eases one potential change (changing the project folder, which would imply changing two path strings in the original code but one in his), but at the same time makes a whole bunch of other potential changes much harder (or even impossible) to handle. We all would have been better off if he'd just left the duplication in place.
