question about the heat map (Score 2, Interesting)

Okay, after taking a look at the article, the press release, and the associated images, I have a question about the pattern of recorded temperature on the surface of the planet. If the hot spot on the planet is offset by 30 degrees of the substellar (high noon) point because of a predicted 6,000 mph jetstream to the east, why then does the coolest equatorial temperature show up directly to the east of the hot spot? In other words, why doesn't the long orange tail of mid-temperatures extend to the east of the hot spot instead of to the west? Is there a basic principle that I'm missing here, or have i conceived the whole situation incorrectly?
