Seems a bit weird - this sort of thing usually happens if a verified rights holder reports a listing to eBay (eg a verified account owned by a brand, like Louis Vuitton, reporting listings of fakes etc).
Titles of books aren't protected by copyright so it'd be weird if someone reported it for having the same title as another book.... How was it delivered? As in, was it a physical book that would be posted, or was it an ebook? Digitally delivered items are not typically allowed on eBay so if it was not a physical item that might have more to do with it than it actually being "counterfeit".
