True, it does. But only to a driver that rules 112 and 113 apply to. Neither of those rules apply in your case of indicating right beyond the first exit (edit, just to clarify, beyond the first exit and up to the halfway point of the roundabout. The right indicator is required if the vehicle intends to exit after the halfway point).

As I said, those rules are silent on what a driver taking an exit that is halfway around the roundabout is supposed to do. It could, therefore, be implied that no signal is required.
