Setting the policy sets up the directory Chrome uses for downloading files. It uses the provided directory, whether or not users specify one or turned on the flag to be prompted for download location every time.
Leaving the policy unset means Chrome uses the default download directory, and users can change it.
Note: See a list of variables you can use ( https://www.chromium.org/administrators/policy-list-3/user-data-directory-variables ).
