This is the law in Illinois, too. It, in combination with the way the lights are timed, makes some intersections particularly challenging for pedestrians.

The basic way the timing goes is: traffic light changes, pedestrian crossing signal illuminates, traffic going straight that squeezed in on the yellow finally clears the intersection, cars turning left finally get a chance to go, pedestrian can finally safely enter the intersection with approximately 10 seconds left to cross a four lane street, lights change again, cars start honking at the older person with mobility issues who could only get halfway across the intersection in the time they had available to safely do it, impatient driver from further back in the line who doesn't care to figure out why the person in front hasn't started moving even though the light has been green for five full seconds swerves into the right turn lane and guns it, narrowly missing the aforementioned older person with mobility issues as they blast through the intersection.
