It's not clear to me. I put myself in the co-pilot seat and I still think the pilot is referencing the island comment to my radar target call, and the ALTITUDE warning was either missed, or it was not responded to in a formal sense required by an SOP. You can't be responding to a system generated warning in the way it was responded to because that has resulted in ambiguity. The comment might have been in relation to the warning, or it might have been in response to the co-pilot radar target call. Hence why a system generated warning must always be responded to in an SOP'd formal way, by both pilots.
