Answering myself: plymouth (99% sure) is caching passwords and systemd
requests the cached passwords from it. Removing plymouth I'm asked for
the passwords from the initrd (no plymouth) and then systemd for the
third partition. With plymouth in my system plymouth is asking for the
passwords and systemd can fetch it from there...

I'll dig more in the code but that is what caused all the confusion for
me!

Cheers,
