I think that's fairly long-winded to explain but rather simple
The cutting of the cards is a bit of a wheeze. When the cards are all collected back together again, the 3 cards will always be in positions 10, 26 and 42 in the deck. Then when you're doing the Up Down bit, you change the order on the 2nd deal and it should all work out from there.
Used the constipated mathematician's method here i.e. worked it out with a pencil.
