The amending votes clause is probably more to do with (I doubt this happens) betting scams and that.

Say someone got a HM on 50/1 to leave (like aaron and jay were in the eviction where there was 5 up). Say a group of 10 people put 2k on between them. And then every one of them spent the next few days creating fake FB accounts to beat the 500 votes limit, and spent a few grand on phonecalls just to get their winnings from the bet. It would be worth it, as they would be getting 10k each. But I think if BB discovered this was going on they may discount the votes as whilst multiple votes are allowed, multiple voting on that level is clearly wrong and might even be illegal(if in conjunction with the bookies or something)

This is just an example of why I think they might have that clause...
