Usurper factions (X for Y) in vassal kingdoms do not work the way my intuition says they should, though I hesitate to say it's an outright bug.
I got usurped as King of Bohemia, holding two ducal titles in the de jure kingdom of Bohemia, and found myself a direct vassal of the Emperor, rather than of the kinsman who got installed in my place. This seems... odd.
