The objectives of the Gettysburg Address were entirely political and did not require the audience to keep track of detailed information with complex interactions. I was at a talk by Norvig recently. I can't remember whether his slides had bullet points, but there were definitely series of single-sentence, loosely related paragraphs. So he might have changed his mind, or you might have missed the point.
