Have the Sampler always recording, set it's limit to the amount of delay you want?

I think the Sampler features twice in that video - once where Thomas had 20 instances of the Sampler in a patch so he could build up a bank of loops as the dancer moved across the stage which he then composited atop each other (perhaps this would work for you?), and again with a dancer's face where he has one instance and manipulates the Offset to jump about the immediately preceding moments.
