Improves cases in which DELETE is used to remove all of the rows in a table and replaces it with TRUNCATE which improves performance as it does not scan each row individually before deletion. This also resets the identity column where applicable.
In the case where the DELETE statement outputs to a temporary table, the insert takes place before truncation.
Going forward, this would mean that a user executing this would require at least the ALTER permission rather than DELETE.
