Hopefully the following info helps you out. Most characters with a projectile can do similar things in the corner. Meaty fireballs are very strong in general, but Round Wave recovers very quickly and is especially dedicated for it. The reason why "it doesn't work on some supers" is because by design Lv 1 supers that do have invincibility are Strike and Throw invincible, but not Projectile invincible. EX-DP type moves and Lv2+ Supers (that have invulnerability) are fully invulnerable. Every Lv3 Super has full invulnerability. Being +10 and right up at your opponent's nose is a great setup for shimmying, too, so he can make use of that, but most meaty projectiles like this are vulnerable to being Perfect Parried on wakeup or responded with an invulnerable move so be careful. Also Raging Demon has 6f of startup before the flash so it will lose to anything that is meaty or most frame traps.
