Based on the CLA SSD4 expansion pack's promo video, I'd say he "pre-produces" each drum in the kit being recorded to the max before he even commits it to tape, so to speak. Even if he does it afterwards, it's still, I'd say a procedure he's become accustomed to going through before commencing mixing. He knows his sound and could probably concoct it in his sleep.
Maybe that's why all that stuff was missing from the tute; it's his secret sauce, after all, and IMHO it's probably a bunch of outboard compressors and EQ.
