Rose's Ultra 1 Glitch

Hello i have a Glitch that not many know about that is the Ultra 1 Glitch thats still in ultra and has been going on since Vanilla. it goes like this: If Both Roses Ultra At the same time and are just at the edge of the hitbox. they both get pushed to the ground from nothing and both ultras get canceled. Its really hard to do but its really odd. i dont have a camera so i cannot show you Visual proof. but you know you got it right if she stops talking and gets thrown to the ground. I AM NOT TROLLING BTW THIS REALLY DOES WORK.

Not sure if you can call it a glitch, its been around for ever and i guess its just how the properties of it effect each other at the same time.

It’s been shown in video before
