That's correct. The Y DNA test will show you men whose patrlineal ancestors match or, more likely, closely match, your own patrilineal ancestors, whatever the surname.

(In some cultures and ethnic groups, such as Scandanavians and Eastern European Jews, were not used until relatively late in history [well, later than elsewhere in Europe], so the results there often show several surnames.)

In your case it would not be unreasonable to expect to discover your father's biological father's surname.
