Leaning vs counter steering

I’ve been riding for a couple months nowAnd I just learned about counter steering but I still don’t quite understandWhat’s the point of counter steering if you lean your body to change direction. I don’t think I’ve ever counter steered.Just watched a bike crash into a truck online for wrongly counter steering but couldn’t he just avoid it by leaning more out of the way ? He was already on the right side of the rode and out of the truckers way but he decided to counter steer and did it wrong. It makes no sense he could’ve avoided it if he kept leaning right. No?
