To turn right you need to do that and then cross the carriageway you were using but on the opposite side of the r/a, and then cross the approaching carriageway so that makes 4 crosses
No, you don't: turn right onto the central island that you arrive at first, cross the oncoming exit carriageway, then cross the roundabout entry carriageway of the arm you will leave on, then turn right onto the exit carriageway from the central island so that makes 2 crosses.
As I mentioned, that's an unnecessarily dangerous design, but let's not double the danger by making more crosses than needed.
