That is a good point like the Prince Charles crash where the Captain allowed Prince Charles to land and they ran off the runway.
It is possible though unlikely that someone else was controlling the landing?
Unlikely because altitude changes were made to avoid other light aircraft, meaning a decent rate of 2500 to 3000 feet was made to get down to the glidepath resulting in the aircraft being too fast and way above VREF.
Hardly a situation where the Captain would consider it a good time to let a PAX have a go at landing especially on a length restricted runway.
Who was talking on the RT? Was it the Captain? was the voice normal or stressed ?
