It does not work as ness tho, even S1 confirmed it. I dont think its a surprise for anyone that we can bounce of walls to use our recovery again. The Idea behind this mixup is rather to bounce of the wall close to the ledge, avoid to grab it and to use the PKT2 offensively instead of using it to recover. Doing this will you will retain the invincibility from grabbing the ledge (which we would not have if we recover to the ledge, drop ledge PKT2 offensively and regrab ledge). It is also quite deceptive and way faster. Not to say that you can avoid ledgetrumps by doing it aswell.
TLDR: Everyone know we can bounce of walls to recover, This is a mixup that'll help you create space if your opponent is pressuring you at the ledge.
EDIT: Got a quite decent example today
