I installed a breathing foil radiant barrier as you explained.
There are 2 types of foil radiant barrier, 1 is a vapor barrier, the other isn't.
Most likely what you have is breathing foil radiant barrier.(has small holes in it to breathe)
I can't see anyone putting a vapor barrier on top of insulation as it would steam up and rot underneath.
