Q&A: What PDF version for eBooks?
In summary (from the above and the ADE FAQ):

Digital Editions supports a superset of ISO standard 19005-1 (PDF/A). PDF/A is designed to support more secure, long-term information archiving; it is based on a subset of PDF 1.4 (the version of PDF supported by Acrobat 5.0). Additional PDF capabilities in Digital Editions beyond PDF/A include basic encryption, DRM-based encryption, JBIG2 image compression, transparency, and compressed object streams.

I'm not sure that the Sony's support all of these extensions to PDF/A, because all its readers except the PRS-900 are using a very old version of mobile ADE.
In your case, is the Sony example at one of the font sizes that includes reflow? It looks like each box is an image and they have all been reflowed into a line of images. This may even have nothing to do with PDF standards if the text is actual text overlayed on the boxes. Any page that is composed of text and images placed exactly on the page to produce a diagram is going to fail in "reflow" mode - since it is trying to produce linear text. What ADE "should" do in that case is display the complete page (i.e. go back to the small, non-reflowed, font size for this page only). This is what happens on some pages that are a mix of text and images, but obviously not in this case.
On the PRS-600, you may be able to use the small font size (no reflow) and than zoom to magnify the page.
