"World Poker Tour: All-In Holdem" Strategy Question

[Vlorg]

Ok this has been bugging me for awhile. According to Wizard of Odds the basic strategy for 59s is to go all-in (being a hand bad enough to try to bluff but not so bad to fold). So why is 59o only a raise? I would think it too should be an all-in (or a fold even). 59o is clearly a worse hand than 59s. The expected returns are posted as well and the numbers seem to suggest that 59o is indeed a raise while 59s is all-in. What am I missing?

I lost my notes on the perfect strategy that David posted in the newsletter months ago so I can't compare.
