I don't think the rule reflects any NFHS desire for a game to end in any fashion but rather an acknowledgement that it is possible for the defense to gain possession of a live ball in the offenses end zone and that a touchdown in such a situation would eliminate the need for the defensive team that just scored to take a turn on offense. The only way around this would be to contradict the definition of a touchdown, which is possession of a live ball in your opponent's end zone.
Ultimately I think it is a measure to account for something that could happen, however improbable, and if it were to happen reward the team that scored as it feels is consistent with the rules.
