I think it could be a little more complicated than that.....
Like, if the owner of the domain also shares the same intials and surname....
If the content on the website has nothing to do at all with the cricket captain. The owner could even argue that the name has sentimental value to him for whatever reason....
If the owner deliberately tried to sell the domain to Dhoni or has content that is directly related to Dhoni then chances are his will lose the domain
