I think it further stresses the point, that captain was not comfortable in manual flying skills. If the report is true, he was overwhelmed and in tunnel vission. His sensory system could not even handle more info, such as being able to check a set go around altitude.
I think it could also stress the point that Capt MAY have been trying to fly the HUD with a set of circumstances / energy vectors / Accelerations, he was not familiar with.
