I have a setup where I have two jars, one void and the other is a Thaumium jar from Thaumic Additions: Reconstructed (though I have also tested with regular warded jars).
The infuser will always put the essentia into the void jar no matter if the other jar is labelled or not. I understand the intent is that it will prioritize partially filled jars over empty ones, but I can't imagine this is intended.
Using Thaumcraft-1.12.2-6.1.BETA26.jar (latest as of 1/6/21, link here)
