Ledge...Phantom Attack?

@SmashHighlights So apparently you can get hurt even when you're on the ledge. That Ganondorf took 5% damage without knockback (36% to 41%). pic.twitter.com/gWpegxOQiO

Firstly, shameless Twitter advertisement. Secondly, sorry about the video quality. I don't have a lot to work with, but there is something strange near the end of it, when Ganondorf has 36% damage. Now to give a little rundown of how Toon Link's D-Air works, there's a landing hitbox on it that deals 5% damage and some horizontal knockback upon the opponent (this is evident when testing above the soft platforms on Ganondorf with Toon Link).

Well, when Ganondorf goes for the ledge, he does not actually get sent into a knockback status like he should, but instead, he takes the damage AND still gets onto the ledge. I've been unable to replicate it, but it's so phenomenal on what one can actually see happen in this game. If anyone else knows how the heck this happens or what the heck this is, please do tell me.
