Well done Rob, I think your interpretation is spot on: a mis-reading of the original intent of the quote.
I cannot say every fact in my books is 100% correct, either (or any technical history book, for that matter): blunders like that by authors are bound to occur, but we all do our best to bring other enthusiasts the fruits of our original research. I did a book review for SMH recently about the Aust WW1 Centennial History, and felt I had to point out a significant error by a well-respected historian, so it can happen to the best researchers/authors as well.
Thanks Hanno - my ability with cross linking etc is non-existent!
