The Kindle treats each page of a PDF as an image that it scales to the width/height of the screen. You can zoom in and move around, but it's not at all like reading a book. Given the PDF format, this is really the only way you can really deal with PDFs that might have images, columns, etc. Much more inherent formatting than with just a text .mobi.
