>> I really doubt that corporate management is intending to be vague/confusing for the sake of instigating discussion or thoughtfulness in the title of mid-management.

I wish I had a source to quote you, my google-fu is failing me now but there's a school of thought that, in a mature organization, the primary role of the executive leadership team is to manage corporate culture. If the leadership team is trying to foster a culture described by the term "servant leadership", then they definitely would want to provoke discussion of what that looks like and how that's different than other organizations and cultures people have worked in.
