Yes. But it is expecting a drier summer to rest through, not
a freezing winter to survive.

It's rather odd that no dormancy is mentioned for this one.
That would be like saying Mexican Pinguicula don't have a rest.
For several months, Cephalotus makes flat non-carnivorous leaves.
This reminds me of how many Mex. Ping. produce leaves w/out traps
in the winter. In both cases, the plants slow down and produce
their inexpensive leaves and return in the Spring and early
Summer to flower (though it's in reverse for Cephalotus.)
It's not as though either sort of plant stops growing completely.
There is no reason for it like freezing or super hot or dry
weather, but they still need to *feel the seasons* in order to
stay healthy. All plants from temperate locations have to
be given seasonal day light/night time schedules to remain healthy.
This is why most houseplants are tropical. They don't need this
and are, hence, easier to care for.
