Purposeful scanning behaviours like the layer cake pattern benefit from clearer contrast between sections, paragraphs, and other blocks of text. If each paragraph and section are undifferentiated to the reader's eyes, their eyes have to work harder to distinguish between different sections as they scan. On the other hand, if each block of text is distinct from other blocks, the reader's eyes have clearer signposts to aim for as they sweep through the text.
