Default Hw5 q8 data permutation

I must be missed something, but I do not understand why we permute the data.

\nabla E_{in} = -\frac{1}{N}\sum_{i=i}^N \frac{y_n x_n}{1+e^{y_nw^{\top}x_n}} treats each data point separately, but then sums them all up. Thus, even if we do permute the data points, in the end it all gets combined together in this sum. What am I overlooking?
