I think you can check off everything on this list and still write inscrutable code. The worst code I've seen is code that was written so that only one person understands what's happening -- the author. Typically the code has too many branches and ridiculous call stacks. The writing analog is a run-on sentence.
This usually happens when the programmer at fault is really smart but still hasn't learned that at some point in the future, someone needs to come along and understand the code he/she wrote.

Maybe we need editors?
