It’s not a nonsense statement. Mojo being a strict superset of Python means that all Python code is valid Mojo code but not vice versa.

JMS in 1994: “Yes, since you've sussed it...the plan was to turn Delenn from male to female in "Chrysalis," in my original plans, as well as making her half-human. And yes, it would've had one hell of an impact...but my concern when I made that decision not do do this back in the pilot was based on the reality that we couldn't do it well. The "male" voice, altered by computer-enhancement, just sounded REAL bogus; we couldn't get it right, and I had to decide between dropping it, and doing something the people would rightly describe as lame all season, just for one big payoff. It was a tough call, but it had to be made.”

JMS in 1992: “What we have, basically, is a female actor playing a male character. Women simply *move* differently than men do; the gestures, the tilt of the head, the smile, it's just a shade different. So you now take that, and wrap it inside a male character, aided by prosthetics to make the face and body more masculine. Now, when you look at the finished product, you are looking at a male, but there's something wrong about it somewhere, and it makes you a little uncertain. The first time I saw Mira in full makeup, it looked great. And there was something very unusual about it, that sense that your eyes and your brain are in conflict somewhere about what you're seeing.” JMS in 1993: “We'd originally planned to go for a more vague sexuality for Delenn; a male physically and primarily in the voice, on top of the natural female movements one gets from an actress. In post-production, however, we couldn't get the voice to sound as good and male as we'd wanted. In addition, a couple of convention showing of a rough cut saw people responding VERY strongly to her voice as it was, so we finally decided to let it stand and change the one reference to "he" to "she," and that was the end of it.”

Given that this was the original plan in the first version of Babylon 5 — hence Mira Furlan’s different makeup in The Gathering — I think it’s fairly likely that this will be the case.
