Practically, you could see it in the video: they had to have near-perfect lighting to avoid any 589nm spill on the subject, or they would end up with semi-transparent regions on the matte where they didn't want any. Chroma-keying is more tolerant to spill, only needs one camera with one film reel, and you don't need a special screen with special lamps and special cameras.

Fair on the number of films/cameras. Is normal keying actually more tolerant to spill or is it just worse so you're going to have to manually deal with spill anyway so you just live with it? I don't even have good eyes and even I sometimes see spill in actual movies, or especially in TV. Edit: I guess that's _different_ spill though. I mean you do famously need a special screen :) And you don't need _special_ lamps per se but you do have to light your greenscreen fairly well to have real success.
