The results from the article -- that you are faster at recognizing across-category changes than within-category changes -- also hold for Russian speakers and the two blues. See:
Winawer, J., Witthoft, N., Frank, M. C., Wu, L., Wade, A., & Boroditsky, L. (2007). The Russian blues: Effects of language on color discrimination. Proceedings of the National Academy of Sciences, 108, 7780-7785.
Moreover, if you make people do a verbal task at the same time -- say, repeating a word aloud -- it makes this effect go away; but having people do a spatial task at the same time doesn't.
