Strictly speaking, what makes Fusion different from Jogress is that the resulting Digimon remains the same Level as its components whereas Jogress results in a higher level Digimon hence why the former is often used for Ultimates/Mega level Fusions like Omegamon.

Likewise Mode Change is defined as when a Digimon becomes a different version of its current species, whether through Slide Evolution or actual Digivolution though most cases of Mode Change are treated as the latter with Cyber Sleuth being one of the few times it's treated as the former.
