Mictlan dominion spread: Did I get it right?

[tinkthank]

Mictlan's dominion does not spread unless blood is sacrificed; fine. Do I understand correctly that this means that
- NEITHER the home capital
- NOR the prophet
- NOR the pretender
- NOR a temple
spreads dominion via the "temple check" method listed in that excellent article I can no longer find? (And hence means that a prophet for Mictlan is simply a +1 holy bonus?)

OR.... is it that ONLY the home capital and temples do not spread dominion?

thank you
