Yes! Exactly, it's a distraction. There are reasonable, well-intentioned reasons to argue that division by 0 should be an acceptable operation in a computational setting. Computational settings need not admit all the rigor of theoretical math. I wish the author had not tried to involve field theory and programming like this because it detracts from the point :)
