I see no potential difficulty in this, unless. of course, the rider has a neck or spinal problem that prevents them from turning 180 degrees to look behind her (in this scenario, I would probably not want to rely on a mirror to assess the situation from behind.
That's one way of doing it, and it's consistent with the NACTO approach of separating conflicting movements (such as paths to the right of right-turn lanes) by time instead of space, the tradeoff being the delay in waiting for the conflicting movement to clear and having to watch for additional turning traffic.
