Yeah I can confirm this existed in Melee... I never really found much of a use for it, though, aside from slightly speeding up how fast you could get on a ledge (but if you miss and just upB on stage, the opponent gets a free return)
because Link is in the air with this move, if it hits, you get the multi-hit knockback from an aerial upB, rather than the super knockback of the standing upB... so it's not amazing as an attack. It's a mixup of sorts for getting on the ledge, but I think it's not much better than a flashy tech.
That said, I kind of hope somebody proves me wrong here.
