I think tool like this can make sense if you cannot read the code. Probably this still gets confused like humans do when variables and functions are named less clearly or even plainly wrong. I wonder if reading explanation like this makes you more likely to believe code is correct, even if some details are wrong. In this signature example, you can read the wrong header, calculate hash the wrong way, compare hashes wrong way, etc. there are some many tiny mistakes.
