Because saving & restoring the graphic state is the safest thing to do in an arbitrary content stream.
The CTM will be whatever it was when you entered the stream - since that's part of the state stack.

Firstly, I've noticed that when I create a new PdfContentByte (using GetUnderContent from PdfStamper) the new PdfContentByte always appends q (save state) and Q (restore state) to the end of itself. Why does it do this? Secondly, what is the CTM if you restore state (Q) back to the first q from the first content stream?
