I don’t see any anecdotes in the article which are cited in support of the idea that different editions of Office on different size tablets cause confusion. Rather, the author uses arguments from common sense.
And confusion does indeed abound on Windows RT. When Samsung executives justified not launching Ativ tablets in North America, citing weak demand and customer confusion, certainly they were not basing this decision on anecdotes.
