Karen writes about a chomed pressure plate and film without antihalation backing causing double images here:

I'm sure there are more articles where I have read of the same effect but this was first to pop up.
Oh I don't doubt it could occur, simply that having tried myself it I didn't experience the the problem.
A bit of kitchen foil of course is much less reflective than polished chrome, and in your link she notes that the problem arose only with slide film but was OK with negative film.
