When the CX accepted the visual he was instructed to maintain visual separation but not pass the aircraft. Many airports have very closely spaced runways and the aircraft can fly almost in formation. For awhile they were trying to establish PRM approaches for such airports with a “zone of no transgression” and a monitor approach controller. It’s all in an effort to increase arrival rates.
This is why I said "legal or not" in my post. There's no point quoting the AIM, there's a distinct lack of airmanship by all parties. The book of rules won't save you from a disaster, airmanship will. Just ask Sully.
