If you can't read code, you should not be modifying it! Sure, a little documentation about WHY does some function exist is often helpfull, in case of this function I do think the only needed documentation is the name. And if at all the comment about why is the data sorted this way belongs not next to this function definition, but next to its use. Though it's hard to say as this is the only thing we've seen from the code.
