But they don't have to remain at the stop light if it's clear, so it does change the circumstances. Now a cyclist can get through the intersection without having to wait for the signal to change if it's safe (a judgement call they make based on what they can see and know). This means they will be gone before the circumstance described in the part of the quote that you dropped:

> For example, if you are a cyclist who has to stop at a red light and a car comes up that is turning right I know that sometimes creates a hairy situation if there is not a dedicated turn lane and the car might try to turn in front of you. [emphasis added]

This will help to create or maintain separation between cars and bicycles at intersections (in theory).
