I am so sorry, but I must have missed answering this question at the time it was posted.
The asterisk under column names is indeed new in 14.0 and represents the number of rows in the table. Therefore there is no column name associated with that number of unique values.
If you have access to Teradat orange books, this is documented in Teradata Database 14.0 Statistics Enhancements Page 16. That orange book explains all of the new changes for statistics in the 14.0 release.
