Their strategy is to acquire more farm more quickly than their opponents, and one aspect of that strategy is to guarantee Dragons on the respawn timer. They're giving up some summoner slots for the triple Smite, and because of that, they need to alter their play. Everything in the game revolves around their farm, and that entire gameplay is considered a strategy of which the triple Smite is a part. A tactic might be to hop over a wall at a certain time, but a strategy involves a coordinated effort toward a long term goal, in this case, lowering teamfight and ganking capabilities while simultaneously increasing long term gold and buff control.
