This maneuver requires high thrust while 'slowing down'. Not sure if that's a reasonable energy trade off. Would you go into a dogfight with external tanks still on? Sure the pursuitor jet won't (rather should't) be in such close proximity position, unless intending to shoot the enemy with his handgun. Thus with reasonable separation, this at best may force a break of the lock, but at the same time slowing down and with extra fuel loss. It is fun to watch at shows, though these days these wows are awarded to the vectored thrust tricks.
