There are “Vice Presidents” of things who don’t preside or directly assist in presiding over any assembly of people. There are “Managers” who don’t manage anyone, “Chief X officer” where there is no other officer for X, or anyone else doing X. Etc. Many of these terms are formed from words originally denoting a specific function, or explicitly making a comparison with other people, not just indicating a “level” of status, trust, bigshotness, etc.
