OK, I think I’ve just answered your question in my response to your other comment, but I’ll give a brief version here.
If there is a bit corresponding to AIXI’s future action, then by AIXI’s assumptions that bit must not be observable to AIXI until after it takes its actions. As such, models of this sort must involve some reason why the bit is observable to Omega, but not observable to AIXI; models where the information determining Omega’s prediction is also observable to AIXI will be significantly simpler.
