Yeah, this is pretty silly. Following and recognizing phonetic patterns from science / fantasy fiction naming tropes isn't a "secret language."
Ask a person off the street to come up with an "alien planet in a science fiction TV series" or "deadly gas/virus from a comic book" and you'll get similar answers.
Your average person on the street could probably successfully come up with trope-fitting "evil alien species" and "peaceful alien species" names, too.
And if you asked the average person off a street somewhere with minimal exposure to English and Anglo-American culture to come up with names, and they'd probably come up with something completely different derived from their own cultural tropes and neighbouring foreign languages.
