Dap, yes it should matter if a person doesn't own the land. The safety zone is for the protection of buildings and occupants, who owns the land the hunters are on does not matter. If John Doe lives in a home and distance of the home is 10 yards from farmer Brown's field, I am sure you don't believe Farmer Brown or his guests should be able to hunt right up to John Doe's yard. Land ownership doesn't matter at all. If I own a farm and I rent the house to someone else, I still have to respect the safety zone of the tenants even though I own the house and out building the tenants use, unless the tenants grant permission to hunt closer than the safety zone. I don't know how many people know it but it is unlawful to shoot through a safety zone even if the hunter is outside the safety zone when the trigger is pulled. Even with shotguns with the ammunition we have today compared to the ammo that was available when the safety zone law was initiated 150 yards probably is not far enough to prevent injury or damage depending on the size of the shot.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
