You have a STOPPING line that is on YOUR side of the crosswalk. That is the line you stay behind during a red light, if you stop then cross the line and stop again in the eye of the law it's no different than if you hadn't stopped behind the line at all. You are correct that it's not compulsory to turn right on a red, however, if you are going to turn right you can't just stop in the middle of the intersection you either stay back or you go.
