Even though you specifically asked Paulo for an opinion, I'm going to provide mine too. :-)
The logic behind having a PdfGraphics2D class is that a wide range of existing applications that are already designed to render content on a Graphics2D context suddenly gain the ability to generate PDF output with little or no additional effort. So PDF versions of charts from JFreeChart, Chart2D, JChart, etc. can be created, GUI applications with printing functions can now print to a PDF file, UML diagram editors can create PDF versions of the diagrams, and all kinds of other neat things. Furthermore, people who already know the Graphics2D API can start productively creating graphical PDF content without taking time to learn the iText API in depth. A little runtime overhead is introduced in the process of translating the API methods to the iText methods that do the actual work, but a vast amount of code writing is avoided. If JFreeChart is used enough for PDF charts that somebody finds it worthwhile to spend the time to write code that uses the data in a JFreeChart object to call iText methods directly in order to cut out that overhead, there's no problem with doing that also. But in the meantime, we have something that works fairly well for JFreeChart and a bunch of other libraries as well. Being able to draw something to an image, GUI panel, PDF file, SVG file, or printed page without writing separate rendering code for each output is incredibly useful...
