I took another look and decided that the left lanes are pointed directly at the outer lane on the roundabout in each case, and therefore the idea of the lane separation on approach is probably designed to encourage vehicles in lane 2 on approach to go directly into the inner lane on the roundabout.
I didn't feel the need to explain this as I thought it was reasonably evident after a close examination.
