I think ultimate is used in the sense of last, final or latest as in
being the last or concluding element of a series; "the ultimate sonata of that opus"; "a distinction between the verb and noun senses of `conflict' is that in the verb the stress is on the ultimate (or last) syllable"
Thats how I read it anyway
