Once a plant is in a location where it couldn't possibly grow outside if left to its' own devices, a lot of the info about what/when it "should" do go out the window and you're in uncharted territory unless someone else has an anecdote from the same conditions in which you have that plant.
It's also not always clear if anecdotes/advice are about outdoor plants in the ground, or potted entities that are inside a house, or greenhouse for winter. Three vastly different environments but not yet specific enough to discuss in general. There can be some confusion about hemispheres if specific months are mentioned.
Plants that experience relatively steady conditions may not experience a dormancy at all.
One has to wonder about day length for tropical entities brought to higher latitudes, where there are wild fluctuations.
For some temperate plants, dormancy is necessary, not just a response. They will either die or fail to bloom in a climate that doesn't have enough hours of cold for winter. I know many examples after moving from OH to AL, both moist climates, but does that apply to any C/S? IDK. Maybe some Alpine plants? Some Sedum/Hylotelephiums?
