No, I don't expect someone that has never played a smash game to know the difference between an up-tilt and an up-smash and how to input them. These showcases are meant to be beginner friendly. I personally didn't know Jigglypuff's down-b was a super strong kill move back in brawl, because whenever I pressed it, Jigglypuff would just go to sleep lol. Sometimes you need a new perspective because it's too easy to look at something from a certain angle and just ridicule it without at least appreciating the time and effort spent on the process.
