OK. Personally, I think his focus was more on reaction time than OODA loop and a simplistic view at that. The OODA loop is not merely a defensive strategy, it's predominantly an offensive one. We are constantly running loops, orienting, deciding even in everyday life, like driving.
In this example, the perp is inside (The preferred place.) the officers OODA loop by walking to the truck. Perp has engaged a process that is causing the officer to decide what to do. THIS is the critical juncture of the OODA loop, causing the opponent to go into the OODA decision process. And this is where battles are won or lost, not how fast you draw. As he demonstrates, physical reaction times are somewhat fixed. You can only go so fast. And reacting to someone else initiating is almost always a loosing proposition. The key is to get the other person to react to YOU. You do this by resetting the other persons OODA loop, even when they have already initiated a process.
In this case, the perp initiated a process, by walking to the truck and this has caused you (the officer) to go through an OODA process. "What's he doing? What should I do?" You get locked into the decision process that eats up valuable time, while he continues executing his process. You already know you can't react fast enough if he draws a gun. So, what do you do? In his example, he says you shoot, which may not have the desired outcome. This is cheating on the reaction time, jumping the gun as it were, but is there an option? Yes, you reset his loop. How? By changing the parameters of his OODA loop. MOVE! By changing you position, you have altered his OODA and he has to recalculate, kinda like when your GPS sighs and says "Re-calculating route." He has to Observe you, Orient to you, Decide what to do and then act on that.
Move to a position of advantage, like behind him with your gun on him, where it would take longer for him to shoot you and revealing the gun. Pin him against the truck or even go to the other side of the truck or behind cover. Anything to cause him alter his plan and make him start reacting to YOUR actions. This could by you the valuable time to Observe he is really a threat or just stupid. A fundamental concept of the OODA loop is that we take time to process our environment. And once we decide on a course of action, it takes time to deviate from it.
Just how I see it.
