this issue also happened to me but i was buyer at that time...So i quickly Create that email ID to check weather it exist or not..luckily it is not so i rush to godaddy and create new account and get it in there...then i added this new account to my old account and got this domain...
I feel it is depend on Domain niche and name of domain... Google can determine words abbreviation...like gift4you can be match with "gift for you"..
as i had domain in past and got traffic from search engine with these kind of keywords...
