Even more foolishly in that situation, the owner of the county of Alexandria declares a de jure war on the pope, wins, hands off the barony and then the pope gets it back automagically a short while later (assuming all Miaphysites involved). Then after the truce expires we rinse and repeat. If you land the holy order they spend a lot of time pressing claims on co-religionists too, which doesn't seem right either, not just because it's not so holy but also because i thought joining the order meant abandoning claims.
