That's a good example of why arm strength is important.
It should also be taken into account when things don't go right & the QB has to make something happen. Throwing on the run, throwing off his back foot, not being able to follow through, throwing across your body... all the things you're not supposed to do, but inevitably have to.
A strong arm can compensate for not being able to set your feet right or other conditions that are less than ideal.
