I think you get confused by the fact that symbols are used as face
names.  For font lock keywords, faces are specified via face
expressions.  You specify a variable above, so its value has to be set
(to a face name), else you get the unbound error.

Instead, you can directly specify a face in form of a symbol, and since
this place is evaluated, you need to quote the name.

It's a bit weird in Emacs that faces effectively use a separate name
space, but they are specified as symbols, and in some cases, variables
having the same name as a face are bound to that face name (symbol).
