This sounds completely alien to me and I'm from a country that uses roundabouts extensively. Indicating before you get onto the roundabout and keeping that indicator on the whole time just sounds very wrong. Also changing lanes at will is odd. You join into the inner lane if your exit is after 12 o'clock, and then indicate your exit after you have passed the one before your intended exit. 'Passing' on a roundabout is also a strange phenomenon I've never really seen before (unless it's unintentional of course)
