Make one author's name bold every time it shows up in the bibliography (when there are two author's with the same last name but different first name)

Question

This answer (Make one author's name bold every time it shows up in the bibliography) works fine, but when there are two authors with the same last name and different first names it makes both of them bold. How can I make only one of them bold?
