Have you looked at the content of the lessons? We're not talking about Currying and modular arithmetic. We're talking about "print", "ask", "is", "forward", "turn", "random". None of these are jargony, and the Hedy examples are carefully curated and designed to hide the mismatch between where these terms come from and the extent of their meaning in programming.
The point of Hedy is not to localize programming, the point is to break down the process of learning the absolute fundamentals of programming into bite-sized, completely simple chunks that students can explore, mess around with, build silly and cool things, without having to worry about the minutiae and quirks of real computers. That's why they introduce an "ask" statement that assigns a temporary, invisible variable that can only be used by immediately putting an echo statement afterwards - because they're building up to variable assignment, but they want to show the concept of input first.
