Worst thing that could happen is that he thinks you're stupid. But, even if he does, he should try to write code that you understand.
It's always a good idea to get people in the mindset that their work will need to be maintained by someone else, because they won't be there after they are promoted. So they aren't writing for themselves, but for the next guy, who obviously won't be as brilliant as they are.
