The text calls out "routine use" - this clause is to permit, e.g. the last access date on the account to be the date of access to the GDPR export request portal (deleting the prior value).
The point of GDPR is to force companies to explain the data they retain and show it to users on request. Setting up a scheme where data is retained but is never available to users for export is a great example of acting in "bad faith" that is likely to increase the possibility that a judge will make an example out of you.
