I definitely agree with him about code reflecting one's understanding of the problem and its solution. I don't agree with the poor programming thing though. No one writes bad code on purpose. Sometimes things like that just slip through while I'm focusing on other issues. I do make an effort to polish things up before committing but at some point I have to decide that the code is good enough to push otherwise I'll succumb to perfectionist tendencies. I'm also a solo developer so I don't have anyone to review my code either.
