I dunno, I've heard of some BPs coming out of their hides, traveling across the encloser and striking at someone cleaning the cage, I would call that aggressive. Actively seeking out a target to attack is aggressive, i don't care who you are.
How do you know the snake was targeting the person and not acting out of self defense to a potentially dangerous stimuli? This would no longer be an act of aggression. Its hard to define the behavior of an animal when we have zero insight into what they are thinking.
