Those resolvers are technically for Level3 customers only

There is this comment from a few years ago, https://news.ycombinator.com/item?id=7120248 , linking to a blog post which is now only accessible from the Internet Archive, where a VP at Level3 stated they were public.

I use 4.2.2.x and I do get NXDOMAIN from them, and I'm not a L3 customer. I wonder if they respond differently depending on who you are...
