Firm agree. To me the best way to build a mental model of some code is to be able to quickly answer the questions that arise in my mind as I read it. The order in which these questions arise differ for each reader, and indeed for each intention that you approach the code with. There is therefore no one “perfect linear order” the code could be presented in and the best you can do is make it easy for the reader to construct their own reading order by being able to easily navigate around.
