The same reasoning would apply to “quantum suicide”, where it is clear that we survive all the time; given that we cannot take into account the world where we do not. If in H you are multiplied in W and M, but directly killed in M, you survive in W with probability one. That is why we add p or <>t to []p to transform the logic of belief ([]p) into a probability logic ([]p & <>t).
