blue order, sam rensho is not describing collisions, hes' describing the most expedient and safest way to cross that light he's described.

I also describe the safest and most expedient way I cross on a specific opposing green left signal.

I think understanding ones' local traffic dynamics, understanding intersections you ride thru regularily is important for smooth execution of the ' opposing left hand green' intersection crossing.

There's another intersection, if i take the green left arrow for busses only, i move ahead of traffic approaching a serious pinch point. sometimes by disobeying strict traffic signalization a bicyclist can ride safer than if waiting for the green.....
