Whoops, good catch! I actually did the run multiple times, trying for the best time, and accidentally got the leadership war screenshots mixed up.
I did discover a bug with the Westphalia liberation -- it seems like if you liberate Lippe and/or Nassau as subjects at the same time, the Westphalia liberation is invalidated.
But here is the leadership war of my best run:

And here is the aftermath of just having won it:

You can see in the unification war screenshot I posted that Westphalia isn't liberated, Pomerania was.
