According to the hacker, “all” he had to do was slightly tweak his existing jailbreakMe iOS Webkit exploit (hence the mention of iOS and pangu in the screenshot) and remove iOS specific code from it. Although qwertyoruiop has not provided any proof or release besides a screenshot, the hacker’s reputation makes it highly unlikely to be a hoax (I do not have access to the hack or a Nintendo Switch here to verify.
People with particular sets of skills (Liam Neeson can participate, but I was more thinking of people with a programming/hacking background) and access to a Nintendo Switch might be able to easily verify the claim: qwertyoruiop’s Jailbreak code can apparently be found here for people to play with.
