Soros is a very manipulative gentleman looking exclusively after his own interests. When he says A it doesn't mean it's true, it merely means that saying A benefits him the best.
You're probably right (and you'll remain right if "Soros" is replaced with the name of many, many people), but I don't think you're the kind of source the grandparent asks for; I think they wanted evidence that Soros shorted the euro or something similar.
Even if he's short the euro, it kinda seems that no single famous, connected billionaire can make or break the euro. It's, like, a really, really big, erm, thing. He ought to believe his bet to be correct rather than hope that him talking about it will move the market very much. So if he's indeed short the euro, I'd guess you're hearing his true opinion (which doesn't make him right, it's not like he's never lost money, it just probably means he's honest in this particular instance.)

The euro is bigger than GBP, but:
You do know he broke the British Pound, right?
Your link says John Major instituted a fixed exchange rate regime and made pounds overpriced. Soros didn't even break the news (a German official did), he just made the most profit shorting the pound. I wouldn't call it "breaking the pound" unless you think the pound was priced about right and he made his profit manipulating the public opinion and thus moving the market.
BTW, I found the interview rather trite; he's really full of it.
But if he didn't think it would be true he'd bet the other way. Of course he's going to put his money on what he thinks/thought was going to happen. I can see how it's not true but I think it's likely he believes what he's talking about.
