I like the name "leader," and if its implemented the way I think it will be, I think its an appropriate name.
Right now we don't have a ton of info on how a cleric leads. But we've got good info on how a warlord leads. We have two known warlord abilities, and we have the White Raven school in Tome of Battle as a model.
Abilities like "Feather Me Yon Oaf" are, in my mind, most certainly a leader type ability. Sure, no one HAS to listen. But it lets the warlord issue a command ("shoot that guy!"), and gives his allies a noticeable mechanical advantage if they choose to follow that command. They can elect not to follow, if perhaps they have better things to do, or don't want to end up holding a ranged weapon at the end of the warlord's turn, but they now have incentive to do what the warlord commands.
