The journal's listed standards puts self-plagiarism into a maybe-it-is, maybe-it-isn't light. If Sewell informed them up front that, oh, yeah, this manuscript is substantially the same thing that I published before, then it is up to editorial discretion as to whether they accept it on those terms. If he didn't inform them of that fact, though, that would be against the journal's policy.
