Nikita, if that is true, it would fit into a picture of a "real warrior" who fights until total victory. Somewhere I read that Barkhorn had an astonishingly bad eyesight for a fighter pilot. But once his wingman showed him the enemy, he almost always "bit into the enemy (like a predator), until he went down" (translation of "sich in den Gegener verbeißen, bis er fällt"). Additionally, it also fits with the extremely high number of combat missions which Barkhorn flew - THE workaholic in JG52...
PS: "if that is true,..." does not mean that I have any reason to doubt in your statement
