That's not what they concluded. It discusses redundancy on the next to
last page (pg.4).
"Follow up analyses showed a strong correlation between the proportion of
redundant sub categories and the frequency with which a top-level category
was confused with other categories (r (9) = .76, p < .05). This finding
suggests that a high level of redundancy makes it very difficult for users
to learn to differentiate one category from another."
Still though, it is just one study. I don't know of any others that
address it. It would be good to see one done that involved more specific
content and top level category labels.
