I also read it the way you do. But interestingly, there is what appears to be an Oxford _semicolon_ between items (2) and (3). The inclusion of an Oxford delimiter in one list and its exclusion in another list would seem inconsistent. If anything, the second list is the one that does not need the extra punctuation because the items of that second list are also delimited by newlines and the enumeration. Very weird indeed.
