Okay, I follow the comment this time, but it is a bit confusing because you're
referencing the 'patchset' field in the comment, but not in the code; this would
lead the reader wonder why you were mentioning it at all. Perhaps just delete
the comment altogether?

     return [output_api.PresubmitError(
       'Issue wasn\'t uploaded. Please upload first.')]
   return []
