Single off-camera flash in auto mode

Canon 40D, L 17-40 @ 32 ISO 400 f4 @1/80 Manual mode.
550 EX mounted on a light stand with 32" translucent white umbrella. Auto mode.
On camera ST-E2 triggered off camera flash.

Even when the camera is in manual mode, flash is still auto flash. Since I knew flash light is going to take care of exposing the subjects properly, I chose maximum aperture my lens allowed – f4 – and choose 1/80, as that is longest time I thought I would be able to hand hold my non IS lens without causing shake.
