Not the original reply, but I support the correction here. Regardless of how pedantic/nitpicking it seems, I remember getting confused about this a lot when learning digital signal processing. Simply because its really easy to upsample.. or look at an upsampled result and get confused by that

I think 'upsample' is the root cause here. Technically that is a misnomer.
