It seems that he is saying that 'action-at-a-distance' is something that would violate the 'no-signalling theorem' of quantum mechanics. So he sees experimental violation of the Bell inequalities as evidence for non-locality, but not necessarily evidence for action-at-a-distance in the above sense. I would agree with his conclusion that both collapse and Everettian theories are like this -- non-local, but also non-signalling at spacelike separations. Bruce ### Yes, It seems so. There is - in general - some confusion between 'nonlocality' and 'nonseparability'. Not to mention also 'action-at-a-distance' and 'locality of measurement' and "local causality" and so on. Myrvold et al. wrote something else here http://philsci-archive.pitt.edu/4222/1/everett_and_evidence_21aug08.pdf (general objections to Everettism).
