Hibernate does need swap, because hibernate means that *the entire content of your RAM is saved in the swap* and reloaded from there when power resumes. Suspend OTOH does not need swap, because the state is kept in RAM. That's why suspend needs a little bit of power: RAM needs powe, or it will loose it's memory.
