The story rhymes here, and experience tells us that document verification is an administrative necessity and not just a part of vacation planning.
In the Netherlands, for example, verifying your DigiD or passport for a flight is not a matter of “vacation planning” but a fundamental requirement to avoid hassle.
If the survey did not explicitly ask about the reasons or timing of identity document verification, then the link is at best conditional.
We always checked these things because we must, not because we have time to plan or be “prudent”.
