Why is that confusing? Its perfectly logical. First line says that packages imported in the NAMESPACE should usually be in "Imports" in the DESCRIPTION. It implies there are special cases when "Depends" may be correctly used. Second line is that packages that are listed as Depends in DESCRIPTION should usually be imported in the NAMESPACE file, but implies there may be exceptions - you might correctly have a "Depends" that doesn't have an import in the NAMESPACE. In themselves, those two statements are perfectly logical and consistent. As an attempt to explain **when** you'd put a reference in Depends or Imports or why you'd use one of those get-out exceptions, it makes no claims!
