It's amazing what the human mind is capable of doing. And he's even wearing shoes. If I'm correct that's a handicap for an organist.
Old as the hills, organists have been doing it for as long as I can remember, (Theatre organists were doing it in at least the 40s & 50s) it is fantastic to see live though.
Regarding shoes, NO, it’s not a handicap, in fact playing without footwear is not recommended as you can damage the nerves in your feet.
Here are a couple of videos you might like from Mark Whale, all played lived.

have at least two keyboards on the stand...usually three. The bottom (when I use an arranger) is an old MS-60 or an SD-5. On top of that is the Hammond Sk-1, positioned so I can play left-handed bass, when needed (70 % of the time). On my right hand is an electric piano. Sometimes, over that is a 61 key synth of some kind (usually a Roland 101.
Wish I could use the Hammond on the bottom, but when I need the auto features, they are not easily accessed when on top of a stack.
