You are missing the point. Whether or not the crew think to pull the CVR or not depends not one little bit on what the incident was, it only depends on what they perceived the incident to be at the time. If they didn’t perceive it to have been a near disaster they may not have considered pulling the CVR.
Given they had had so little situational awareness during the incident it doesn’t seem like a stretch to me to think that their lack of situational awareness may have continued until well after landing.
