It certainly does have a dormant period.

I treat my D. cistiflora like a tuberous species. It get watered
by the local opening rains and then stands in a tray of water
over the growing season. When it starts to die off, I remove the
pot from the water and dry it out totally.
I think the confusion whether the pot should be dry or just moist
stems from people losing their plants after hot summers. Just
remember, in the case of tuberous Drosera, the tubers are often
quite deep where the temperature is stable and cool compared with
the topsoil. If you place your pots in the coolest part of the
greenhouse, say under one of the shelves out of direct sun, then
you won't get an increased heat load on your tubers and dry them
out. I think that the same applies to D.cistiflora.
Must be doing something right, it got big enough to flower (for
the first time) this year, unfortunately I didn't get any seed :(
