That's certainly an argument that could be had but Google's position on it is not in the document you cited. It specifies that the maximum royalty Google will ever ask for a standards essential patent is 2%. Whether Google approves of asking for 2% in the case you are referring to is not clear to me. At this point the law suit is way past the phase of negotiating licensing fees and I doubt very much that it is possible to rewind it back to there even if Google wanted to (which I don't see why they would; they know that Apple is intent on banning their devices - Apple's goal is nothing less than the complete destruction of Android as a product, not negotiating reasonable licensing fees).
