It also maintains the /dev/mapper directory, creating inodes there called 'name'. It understands the above three ways of referencing devices: it does not depend on the existing contents of '/dev'. Some distributions chose to configure udev to create /dev/dm-N inodes where N is the minor number. (I have always discouraged that as a recipe for confusion: I believe that using configurable names is a better approach.)
