What are the rules for naming potions?

When a potion can increase weapon critical and spell critical, why is it called ESSENCE OF SPELL CRITICAL instead of ESSENCE OF WEAPON CRIT ?

There's an order on the internal database that determines which effects go first regardless of the herb combination, Spell Crit is before Weapon Crit in all instances because of its naming in the list. Might be by type then alphabetical which would be the best assumption.
