Is this Nina, or Olga?

As Jonathan Rosenbaum writes in the Criterion F for Fake booklet: "If we freeze frame in the right place toward the end of "girl watching", we'll discover that a couple of the full-frontal long shots of "Oja Kodar" approaching us on a city street don't actually show Kodar at all but another woman (her sister) of roughly the same size in the same dress. Given the whole sequence's elaborate peekaboo tactics- a mosaic of almost perpetual fragmentation- it stands to reason that two very brief shots pretending to reveal what many previous angles have concealed can readily fool us by hiding in full view, just like Edgar Allen Poe's "Purloined Letter"."
Rosenbaum implies above that perhaps Nina's doubling for Olga was intentional on Welles's part: It's All True/ F For Fake/Truths and Lies, but could there have been another reason? Perhaps Olga just wasn't there that day; certainly, it couldn't have been modesty, as Olga appears nude extensively in both pictures.
This is a 1974 cover Nina did (the only picture I could find of her):

The cover story of this magazine is "Nina Palinkas: Debut con Huston", and the story inside is "Orson Welles/John Huston"; as it seems she never worked with Huston, but Huston was in TOSOTW in that same year, it seems possible that she doubled for her sister in "Wind" as well as in "Fake", but this is sheer guessing, of course. The question is: how much doubling did she do for Olga/Oja, and why?
