Code of Ethics and Standards of professional conduct

Have you noticed following change (very minor). from the the ninth edition 2005-standards of practice handbook the code of ethics (first 6 bullet points) the 4th bullet point reads : “Practice and encourage others to practice in a professional and ethical manner that will reflect credit on themselves and the profession.” However, there is a summarised TWO pages, ethics available on CFAI website, in which the 4th bullet point says : “Practice and encourage others to practice in a professional and ethical manner that will reflect credit on ourselves and the profession.” Did you see any change in the above two points. One says “themselves”, the other says “ourselves”. I know it is very very minor, but is it officially changed and made known or it is typo error ?

maybe it is directed towards outside world – when they use “themselves” directed towards charter holders alone – use “ourselves”
