Has anyone used the Pyrewyrm Doom Track in The Last Days of Anglekite?

Has anyone used the Pyrewyrm Doom Track in The Last Days of Anglekite? I am confused as to how it should be used. Are “the appropriate preparations” meant to involve completing the first set of bulleted points (which embody “the ritual” I believe)? But that seems wrong because it also says “they can only start the ritual (and use the following moves)…”.

Also, at the end of the Doom Track description it says “Once the Doom Track has filled, the cult may skip directly to completing the ritual”. Does that mean that the first set of bulleted points don’t need to be complete if the Doom Track has been filled (presumably by events in the second set of bulleted points having come it pass)?

I’m inclined to just mash the two bulleted lists together but would I be missing something if I did?
