I think the article may be referring to the directory structure in iCloud, which allows only one level of nesting similar to the folders feature on iOS and in Launchpad. John Siracusa's review describes it[1]: "Only one level of nesting is allowed, and the "folders" are of the iOS variety, complete with tiny icon previews and inline expansion of their contents."
