If you came to the IETF and were working for company X, registered pseudonymously, and didn't disclose IPR belonging to you or company X, and then later company X sued someone for using their IPR, you and company X would get raked over the coals, jointly and severally; the deliberate attempt to deceive would make things worse for you. And that's the point: to provide you with a strong disincentive to doing such a thing. So whether the rules prevent you from being anonymous, or prevent you from suing, everybody's happy.
