He may have made a mistake, or he may not have had a choice about distance. Inside a house, you're either in the room or you ain't. It might have been close enough quarters to force this. Remember, this was NOT the Tueller drill because the Tueller exercise allows/assumes the shooter has his eyes and attention on the knifer throughout. This guy could have closed as much as twice the 21 feet in the drill--that would be roughly 40 feet, wider than any room in my house.
And as Erick points out, if he'd had a stick he probably wouldn't have gotten rushed in the first place--with no threat at a distance, the attacker could have just bolted for his truck and rifle. He did great!
