Its possible I've caught you at bad times but it's been my personal experience that you do not try to avoid HOs at all.
If you're packing superior firepower and are confident of superior gunnery, shooting head on is completely logical.
Though most of the shots in the video can only be called "HOs" if one is deliberately twisting the definition. Shots on roped foes barely able to hang there and aim or front-quarter shots where the foe has nothing close to a gun solution are effective tactics, not to mention common practice in this game.
Don't like HOs? Avoid them, supposedly easy to do. Or aim better and send them back to the tower.
If their airplane goes boom and your does not, you chose the right tactic for the situation. If the opposite happens, you chose the wrong tactic for the situation. All else is rubbish.
