Publishing nonsense is a good way to spread disinformation to your adversaries and waste their resources, likewise to “explain” things you want to keep secret which have vaguely similar properties.
But also in a large organization there will be pockets of incompetence which are more expensive to eradicate than they cost to leave be. If you’re making sure to do zero nonsense, you’re probably also preventing some unexpected quality progress.
Really it's only public because they want it to be seen. Secret research doesn't just end up in a patent database. I have a feeling you 100% nailed that it's just more of a distraction which makes it even more peculiar.

My thoughts as well and the only reason I see for doing that is if they actually have something similar and send out this to pretend they are trying to distract everyone(, or are trying to fool everyone ;-)
