Having preferenes is very different from knowing them. There’s always a process of reflection that refines preferences, so any current guess is always wrong at least in detail. For a decision theory to have a shot at normativity, it needs to be able to adapt to corrections and ideally anticipate their inevitability (not locking in the older guess and preventing further reflection; instead facilitating further reflection and being corrigible).
Orthogonality asks the domain of applicability to be wide enough that both various initial guesses and longer term refinements to them won’t fall out of scope. When a theory makes assumptions about value content, that makes it a moral theory rather than a decision theory. A moral theory explores particular guesses about preferences of some nature.
So in the way you use the term, quantum immortality seems to be a moral theory, involving claims that quantum suicide can be a good idea. For example “use QI to earn money” is a recommendation that depends on this assumption about preferences (of at least some people in some situations).
