How exactly does the dragon soul for a perk trade-off work?

To be more specific, does one need to remove higher tier perks before a lower level perk is removed, or can any perk be removed regardless of placement in the skill tree?

As an example, if I no longer wanted Elven Smithing, could it be removed without removing Advanced Armors?
