Is the Shear Flow Direction Incorrect in Preventing Beam Twisting?

[fonseh]

In the figure , we can notice that the moment due to Pe is counterclokwise , but moment due to shear flow is also counterclockwise , How can the Pe prevent the twisting of the beam ?

Or is the direction of the shear flow wrong ? Should it flow from the below to the top ?

From how I read it: ##P\times e## is the resultant of the shear flow and gives you a distance ##e##, the distance (on the other side of the web!) at which you can apply the actual load that offsets ##P\times e##, thus causing a minimum of twist.

why ? P is the applied force , and F is the resultant force of shear flow, right ?
