Smash Lord
That wasn't a SHFFL aerial, though. That was a juggling sequence started with the final uair being preceded by a full hop. You kind of went off on a tangent with that.https://youtu.be/WclOwdwxYcI?t=4m18s
Here's one example, a common combo on battlefield even easier to land on FFers and in many variations (incl. only one aerial as I've been talking about on flat). This is Vist; the Luigi main, doesn't even really play Roy. And that's Chudat, not sure if you need a history lesson but he pretty much was the first Young Link ever way back in the day...so go actually watch some good Roys and you will see everything I've talked about and more.
SHFFL aerial > Fsmash is literally one of the staples of any Roy player (I've seen M2K, Sethlon, Pyro, Neo, Vectorman, and Ken all use it) just like Multiple D-tilts > F-smash & D-throw > Fsmash/D-smash & U-throw > F/U Smash & CG > Smash can 0-death most top tier FFers with DI following and tech chasing. The fact that you don't know this and are trying to argue it just shows how little experience and knowledge you have about Roy. Run the imaginary scenarios in your head and run the numbers incorrectly on a spreadsheet all you want. I have little to no motivation to make you "believe" since it's a waste of time and you seem quite biased.
Additionally, Chu didn't seem to TDI any of that, with the exception of the first fair which he smash DI'd in and upwards. If Chu has simply DI'd the first or second uair to the left, then the best thing Vist could have done is wet noodled him.
I'll Roy ditto mm you for $20 if you ever come to MN.
