I see what you are saying - and maybe someone can get by in either job without being strong in both skills, but I guess the point I'm trying to make is that all people-management roles ideally have both things happening. So to actually be good/great at roles that people assume are exclusive either to leadership (e.g., CEO) or to management (e.g., good ol' middle manager), both skills are necessary. And the big difference between the above examples is scope/scale, not how much leadership vs management is necessary.
