Why would a garage door torsion spring break & is two better than one?

As for why they break, well, they're a big spring doing fairly heavy
work in possibly nasty weather. Stuff weakens and breaks under those
conditions.
Sure, metal fatigue.
Prove to yourself. Take 2 pairs of pliers and bend a thin strip of
metal back and forth until it breaks.
