Withholding Name fields under Vendor Address - Withholding Alternate Name Not Printing on 1099 Forms

Are the values in the Withholding Name 1 and Withholding Name 2 fields under Withholding Alternate Name on the Vendor Address tab used in place of the regular Name 1 & Name 2 fields on 1099 forms / files for the vendor?

Would the Withholding Name fields need to be populated before payments are produced and/or 1099 data is posted in order for it to be included on 1099 forms sent to the vendor or the IRS file?

A user updated the vendor via Correction mode to add the Withholding Names.  This was after any payments and the Post Withholding AP_WTHD process.  1099 Report Post 1099_RPT_PST was rerun - when the user creates the 1099 forms, the Withholding Alternate Names are not displayed.
