I wouldn't call it a lie. While it would make more sense to have a different escrow in Royse777's situation, as long as the campaign participants trust him (which they probably do as evidenced by applying to the campaign) and are aware that he's the escrow I don't see this claim as false. Campaign manager acting as an escrow is quite common as you probably know 
Good point, I've edited my post.Do we know for a fact that Royse777 has money problems severe enough that he'd be tempted to steal $2000?
No. I still wouldn't trust an escrow with money problems, but in this case, if the casino trusts Royse777, that should be enough. Campaign participants usually join anything they can, so they don't care about it either.
