Where Can I Find This Trick?

I recently saw a video by Chris Ramsay featuring Juan Colás performing a magic trick that really caught my eye.

In the trick, he showed he had 5 cards, a sequence from Ace to 5. He counted them, showing each one, and when he reached the 5, he would count again, but this time from 5 to 9, repeating this until he got back to the Ace.

Could anyone tell me where or how I can learn this trick?

Thanks.
