it's a small point and maybe a different word would have been more clear (because I agree, recidivism commonly refers to committing crimes again after being released from jail), but none of the definitions I found for recidivism were specific to release from jail - the definition seems to be committing offenses again after some type of intervention. in the case of the nutraloaf, you're already in jail and you commit some additional offense (say, starting a food fight). the article seemed to indicate that in most cases, the offender avoided doing the sorts of things that could get them back on nutraloaf - in my opinion, that meets the definition of recidivism.
