He's wielding it one handed. Remember one hand has to be free for sign weaving. His full range is actually almost ten feet overall, but that's well beyond the true edge of the blade. Wielding it two handed would be impossible from the angle. He only had to twist one wrist around after all.

Even one handed eight foot is a push, his sword is 4.25 feet, so a 5ft 11" man is covering over three feet with his arm span?
