The whole point of n-ary Associations is to model non-binary associations. In this case, if Tony needs to know which employee has which responsibilities in which department, then he needs a ternary association. If he doesn't need to know that then he doesn't need a ternary and your statement is fine.
About your issue, I think you need to be clear if you are talking about classes, or tables. In case of tables n-ary associations are not very usefull, since in a relational database you can only have binary associations (foreign keys).
