So I read the transcript of that episode (h/t to @jerwin for finding and linking the transcript!!), and I’m not seeing any indication of three of those being the same apple. The closest I could get to any overlapping types of apples being identical was this single line from near the end of the piece: “Pro tip - if you see Pink Lady and Crips Pink in the same store, just buy whichever one’s cheaper because they’re the same apple.” Wikipedia entries for each of the listed apple types seem to indicate all of them are distinct types, with some sharing of partial commonalities at the parent or grandparent stage.
