I'm guessing that the 'non idol' that Simon & Ben found are just clues to finding an idol. Instead of a written clue - they are material picture clues.
Not a bad idea from a production aspect as they achieved quite a good result within the Villains tribe.
Not only does Simon believe he has an idol, but the rest of the tribe (& now the entire field of participants) believe he has an idol..
This of course can have good & bad repercussions..
Good insofar as he has the perceived belief from everyone that he has a shield of immunity in the form of an idol, thus he might be shielded from some nominations when they think he will simply play it to save himself.
Bad - as at some point the others will want to flush it & thus target him at some point during a tribal vote to make him use it, which could be devastating if, in fact - he does have the majority of tribal votes...
