I'm guessing in this case is that someone tells Whitey exactly what to write due to his advanced stage of dementia. So they would say 'Whitey Ford', but he obviously must have thought they said 'Whitey Four' and simply wrote it out, not realizing his own name is not spelled this way. It's truly sad and has to be extremely tough for family members to slowly witness this over the years for loved ones.
