No, it isn't weird. It provides the guest of whatever age a level of confidence... that it is safe for those who might have a problem to be visiting; think children, elderly, crones disease or hundreds of other requirements a guest might have. It might be something like 250' or under making it 500' apart.. you are either within 250 of one or the other. I am not sure that is the number... but there IS a number they attempt to stay within. Not everyone on this planet is between 13-17 years of age... and even they might require such tight distances.
