In English, the difference between "until" and "as long as" is quite distinct, but in Italian, it's a little blurry because the presence of the negative word non (not) might change the meaning of a phrase or it might not. When the meaning is not altered by its presence, the word, in this case non (not), is "pleonastic." We're talking about finché and finche non.
