I think you did. The article makes it sounds like there were more or as many changes to the US version: "Mitchell was presented with a substantial list of changes for the US edition". And the article makes clear that the author was uninterested in tracking the changes: "'It’s a lot of faff – you have to keep track of your changes and send them along to whichever side is currently behind – and as I have a low faff-tolerance threshold, I’m still not very conscientious about it, which is why my US and UK editors now have their assistants liaise closely.... I really never dreamed back then that anyone would ever notice or care enough to email me about it, or that the book would still be in print 13 years later, let alone sell a couple of million copies and be studied or thought about by academics.'"
