Yes, one source can have two effects which will be opposite one to the other. But these cases leave always open the approach of dealing with them as a total of the cause and its causations. Since, the target is to end up with one definition; even if I had never applied the term “dualism” to describe these cases, I guess the one covering the broader range of interpretations is the more useful, as basically it covers what dualism is for me, but include also another category.
Well that was useful, I can imagine us arguing about some dualistic aspects and having each one in our minds a different description of what we are speaking about.
But, do you insist on using the expression “different states”?
I think “states” leaving many aspects out of description and “different” does not presuppose opposition, two aspects could be irrelevant and still different.
Maybe we could use "elements"?

However, hot and cold also could be argued to come from the same source: stimulation of a body’s physical nervous system, which then subsequently differentiates the stimulation as hot and cold through discerning their dualistic dynamic together in relation to each other.
I will disagree here; body’s physical nervous system is just the medium for our mind to perceive kinetic molecular energy or the lack of it, as “hot” or “cold”. I mean, our perception reaches our mind through reaction of our physical nervous system, but there must be a cause for our physical nervous system to react to it and send the message, (which will be combined with intentions, or expectations etc at that moment and conclude if something is hot or cold, I could characterize water of the same temperature as hot or cold, depending on what I intent to do with it).
