He really is, look at this example:
Jan 8 2011: Stevenage 3 Newcastle 1
FA Cup
Barton’s involvement: Starting XI
Bet 11: Backed Newcastle – £497.50
Bet 12: Backed Newcastle half time/full time – £250
What happened
Newcastle became just the fourth top-flight team to lose to fourth-tier opponents since the formation of the Premier League, with Barton - who played the full 90 minutes and scored Newcastle’s goal - losing bets totaling almost £750.
