Yes, you read it right, it says the controlling agent is responsible for
sending the updated offer, and in section 7.1.3.1 (Failure Cases), it talks
about the effect of a role reversal :
"The change in role will also impact whether the agent is responsible for
selecting nominated pairs and generating updated offers upon conclusion of
ICE."
So a change in role must be sent back from the ICE agent to the signaling
handler (CM).
