Is there an actual definition of what lateral separation is required to not be considered flying "over" someone? Common sense would say that if you are 1" laterally away from a person, you are close enough to by considered flying over them, but if you are a mile away laterally, then of course you are not. So where in between these two extremes are you considered to by flying "over" a person?

I'm curious to know if there is an actual FAA definition to this.
