These reports (#267095 and #284941) complain about inconsistent use of terminology in the update-alternatives man page. I was confused by this too. The man page should follow its own TERMINOLOGY section more closely.
TERMINOLOGY generic name symlink alternative > priority > ... < update-alternatives [options] --install link name path priority [--slave link name path]... > update-alternatives [options] --install genname symlink altern priority > [--slave genname1 symlink1 altern1]...
