Actually our world has been in a recurrent, permanent crisis for long, so it not surprising to keep a pessimistic outlook of markets these days and that is why shorting is the most frequent position in markets for old traders looking for sure bets.
As I said, we don't know his real portfolio structure to make any definitive conclusion, but we can safely assume that every short position Soros holds is balanced (hedged) by a long position in something else. That's likely the only way money can be made consistently in the long run. And Soros is not a prophet, he lost badly (~$2B) in Russian markets in 1998...
He wanted to play the same games as with the sterling, but got fooled himself at the end of the day
