Is it possible it's faster, if the left turn can only go on an arrow, and the arrow is short, then it could takes several minutes to take a left (I know an intersection where it takes over 90 seconds to get an arrow (and can only go on an arrow), but also takes 3 cycles to get through it if your in the back. )
If there is right on red, one could take a right if clear, then cross all the lanes, hang a u-turn, and go straight through the green light...
