Yes, that certainly is true.

But, under unconfined conditions, there could be a preferred direction
of rotation.

Take a paper and pencil to sketch a force diagram to verify
the following:

If there were no head angle (0 degrees), all the force applied to the
handle would produce torque about the center of the bolt or nut.

With a certain head angle, some of the applied force does not produce
torque but rather produces an acceleration of the bolt or nut.  Of course
the bolt or nut is fixed and cannot move, but if the wrench should slip
off then the resulting motion of the wrench could cause problems,
especially if a lot of force is applied to the handle (stubborn bolt).

So, in light of this, which direction of rotation would be preferable?

Note that my original posting contained TWO questions: the reason for
the design and any rotation preference.  The two issues need not be related.
