What's the difference between what's shown on the two pages (sorry, not
watching that youtube video)? You can of course let the ternary operator
return the result of any kind of valid mathematical expressions, not
just constants.

  f(x) = x**2 > 5 ? -x**2 : 2*x

  g(x) = x < 0 ? h(x) : i(x)

That what you mean?

Best, Karl
