lulzYeah Zelda's UpB has many silly properties, with both the spiral animation and the ending animation. I remember when Matthew and I were playing one time, Matthew was on the stage and I was getting back onto the stage so that I could attack Matthew again, the UpB (when I was versing Matthew on FD) finished with me under the level and I was able to use UpB again even though I hadn't landed yet and was able to keep fighting Matthew. Matthew was shocked and Matthew's shock was similar to the shock that I experienced because both Matthew and I didn't expect that to happen so that I could fight Matthew again.
Everyone can do this.
It's similar to how Wolf sometimes won't grab the ledge when he side b's into it but he can double jump again and won't be helpless.
Marth has a habit of doing it too.
Not really Zelda specific.
