I think that person is having a joke at your expense.

And I agree with him about the "what" part. In fact it's very important when you're designing too.

So important that I wrote the WhatNotHow page...

As far as I can see (based only on questions that people have posted here about the certification exams), any code you see in those exams is meant to confuse you. So while you're studying for the exams, don't let yourself start thinking that any code you see there is something that you should write in the real world. Because much of it isn't. Many of the language features that you are tested for are things that you should never do in real code; however you are learning about those features in case you have to work with code written by somebody else who didn't get warned not to use them.

yes, such a code look like a mess.
so i just start from the first interation and write it on paper. then work my way untill i understand the code.
