To specifically answer your question Why is the code1 used if we can use code2  I might suggest that the programmer was thinking in a mathematically broader sense  Specifically  perhaps the broader equation is a power equation  and the fact that both first numbers are  2  is more coincidence than mathematical reality  I d want to make sure that the broader context of the code supports it being var   x   x   y in all cases  rather than in this specific case alone  This could get you in big trouble if x is anything but 2
