The input for this one is simple, but tight. For those of you who are familiar with Melee, it's similar to jump-cancelling a grab. For those who aren't, the input is: Jump -> Toss, if done too slow then it will result in a hop and a toss as seen in my clip.
This tech could be implemented into ground-movement to redirect a roll without losing momentum. Even if you just go into a run out of this, Mario will be in a sprinting state. This should make roll a less high-commitment option.
Edit: Second video I made to show a friend who's early on in the game still, shows a little bit more about options out of it: https://twitter.com/Spire_Rubica/status/926228179705982977
If you're using motion controls on detached joycons, the input is pretty easy to get and the only thing to watch for is whether you're on the ground when you release ZL. If you're in the middle of a bounce, you'll do a midair toss instead which is slower.
