Usually the helmet light is a spot beam and is pointed straight ahead so as you turn your head to look around a bend the light will do the same. There is no nead to have a helmet light pointing at the ground as your bar light will already be lighting that for you and as the helmet light will moving with your head you may find it distracting to have it's beam dancing around on the ground.
Set the helmet light for spotting things in the distance and for looking into corners, sounds like you have your bar light just fine.
