That’s not machete order, the point of machete order is to cut episode 1.
Despite its name, that’s not its purpose. The cutting of episode 1 is only secondary compared to the true purpose of machete order.
The point is not what it’s purpose is, but that the order 4-5-2-3-6 is called machete order and the order 4-5-1-2-3-6 is not. Words mean things.
