Norm,
The part you quoted should be in two lines:
Note the underlined section pertains to higher circles of spells used in the warder glyph, thus the increased difficulty rating.
The varying reagent costs and difficulty are tied to both the spell level and the delivery you want to use - so instead of the caster choosing like most rituals, in simplistic terms you choose by spending reagents and increasing the difficulty.
