Survivor 32 Episode 9 - Just a simple interpretation on how the superidol might work: it can be used on everyone after the votes are read (including the person with the most votes, that's the whole point) but it already has to be 'assembled' at that point in time - i.e. it can't be combined on the fly.
No further footnotes or small print for exceptions needed; you can use the idol like any other idol up to the point Jeff asks if anybody has an hidden immunity idol to play, including giving it to any other player and hence the last chance for creating a superidol.
