Considering that it included a larger and more diverse sample across 12 countries, it may be that the original studies which couldn't be supported were valid but not widely applicable beyond a specific population, or that the results represent a change in how people act from the time of the studies (One of them was an effect based on seeing an American Flag, and I can see how that might have changed).
