Why Shutter Exp mode does this?

Using D300s, 17-55mm and SB-800 iTTL no compensations set.

If I set my D300s to ISO200, manual mode, 1/60s shutter speed and F8 I get a good exposure.

If however I set shutter mode, 1/60s for the same subject the camera selects F2.8. The resulting image histogram is not much different to before.

Why would shutter mode use F2.8 rather than any smaller stop?
