But what number is "universal"? OK, remind me if I forget to comment this, but to explain what happens here I do say a little more on the Fi and Wi. A universal number is just the code of a universal machine or "interpreter" (in a nutshell).

I am not sure to understand the relation of your quote of me and the idea that the order of the computations provides the order of the conscious state, unless you are refering to the logical order defined by each computational state. If you run the UD, some "internal first person future" could be implemented before some internal first person past, buut this has nothing to do with the logical or arithmetical order. OK? I intend to explain a bit more through the use of the Fi and Wi, (= the partial recursive functions and their domain of definition), but it would help me if you could explain what exactly (or more precisely) you mean by "order of computation". First person experiences have to be related to infinities of computational histories, right?
