When overtaking.....
When overtaking, you are TAKING an action that you are RESPONSIBLE for. You've pulled to the inside and YOU need to manage your CHOICE and get back to the outside WITHOUT imposing on the rider you're overtaking. You DO NOT have the right of way. If you're not able or willing to get on past and move back over efficiently and safely, then you shouldn't have chosen to go to the inside in the first place. This is basic stuff, people.
