It's all about intent. Clearly, Heath was doing what he did because he did not measure up to Kai...period! Stomping ones feet or bellowing are quite different in that the bodybuilder is engaging in tactics to psych out the opponent or appear dominant and alpha.
But an attempt to look larger than your opponent by continuously stepping in front of him is not right.
You can manipulate your body to hide flaws etc, but to blatantly and artificially make yourself appear larger to judges and photographers by standing a foot in front of your opponent is a tactic used by morally bankrupt jackasses like the man in question. Arnold used mental tactics to win...not cheap moves on stage.
Anyone can create an alter ego and appear as an honorable person, but your actions show your true self.
