Honestly, I wouldn't know either way. The HT article was debating the source for white strains and said they thought all white strains sprang from White Russian.
Well, it certainly wouldn't be the first time an article in HT contained more enthusiasm than facts, and probably not the last, either.
Here is what Simon has to say about White Russian:
Serious Seeds said:These seeds produce strong, healthy, fast growing plants that are fantastic in appearance and effect. Very popular also for outdoor growing in Spain, France, Italy and California. This variety is our most typically Indica strain. White Russian is a stable cross of our original AK-47 and the famous award-winning clone of White Widow from the 90s.
He ought to know.
