What is the purpose of the marked area between stop lines at some traffic light-controlled junctions?

Explanation: These are 'advanced stop lines', and provide an area for cyclists to get ahead of traffic when the lights go green. You should aim to stop at the first line if the lights go red or amber, but must stop at the second line if you've already crossed the first by the time the lights change, even though the area is reserved for cyclists.
