Revenants are "vampires unless noted", so their rules are subtractive. You start with everything a Kindred can do and you then cross off the things listed.
Ghouls, on the other hand, are "human unless noted", so their rules are additive. You start by assuming nothing and then add any abilities mentioned.
This means that the same wording in the two sections can't be assumed to mean the same thing.
It's a question of context.
