"Thinking I am in front of him, the enemy raises his sword to attack, but lo I am already standing behind him"
"Drawing out the attack of the perverse enemy, my body stands behind him and cuts."
I learn from two different shihan that this is not about evading, but going through the attacker. Which means using the body in different way.
Looking at the result is interesting: After evading the attacker has all possibilities to further attack. After going through him you stand behind him and cut. finito
So what the football video shows is a counterexample to what they want us to do.
