It's weird, but standard. These exchanges are a formal way of fleshing out what the parties do and do not dispute. Both sides limit what the agree to as much as they can with a straight face, and everything is qualified as much as possible to make it hard to pin you down on something later, after you've learned more about your and their case, e.g., they might disagree that TI is the assignee, or that the language is properly part of the patent b/c it was amended during prosecution or by a certificate of correction.
