Water storage

Why does aqua brick say to use within one year? If the water is treated , can’t it stay longer ? Debating between those (I like the 3 gallon size) and the stackable 5 gallons from the ready store but those say with treatment the water can stay for five years. Why wouldn’t I treat and not have to use/refill annually ?
