Unfortunately I no longer have a savefile so I will just describe in detail.
To reproduce:
1) Attract Pather attention on your colony until you get a Pather cell
2) Wait until the Colony Crisis event hits 425 progress and roll the Luddic Path Satbomb Attack Colony Crisis.
3) Immediately reduce your technological use to reduce the Pather attention, in my case, by removing my AI cores, colony items, and shutting down my mining.
4) The Pather cell will "dissolve" on its own, without you needing to fight the Luddic Path.
You are now here:

What I expected to happen:
I expected this to cancel the impending Luddic Path Satbomb Attack Colony Crisis, just like paying the tithe would, or disrupting the Pather cell by attacking the star fortress.
What actually happened:
It seems the crisis is not scripted to recognize this as a possibility, so the crisis event continues like nothing had happened and you will indeed get satbombed my friend.
What's worse, since you technically no longer have an active Pather cell, you can no longer pay the tithe, you can no longer start the Scythe of Orion quest, and killing Pather ships does not affect the crisis progress (see how "hostile ships destroyed" is empty in the screenshot). I assume destroying the star fortress wouldn't work either, but I didn't try it.
But essentially, not only does peaceful dissolution of the Pather cell not stop the crisis, it makes it effectively impossible to stop by any other means.
