Their footnotes are in the form of Jones (2000), which are pointers to entries in their references section. Perhaps part of my question - apart from the thought that we could cut out repetition & arguably make our Notes section more easy to follow - is why we have an additional References section? Answering my own question, it is because it is the easiest form of listing for all refs used ... in which case to my sensibilities, our Notes should merely point to our refs as happens in Night of the Long Knives. As you note, it comes down to preference.
