They could be talking about Esperanto!
It often happens that things in the literature, online and offline, sound just like a property of Esperanto. Here is one random example I just came across:
"A distributed system is a system that operates robustly over a wide network."
See what I mean? I read this and go, "Hmm, 'operates robustly over a wide network'??? - They could be talking about Esperanto!"
