The boat referred to in my earlier post was a Pearson 28, 1982. AFAIK, it had 
the original engine and transmission and an offset prop.
 
Ideally you are correct, assuming the boat/prop/engine/transmission combo ended 
up with the prop rotation 'walk' making up for the offset.
 
In my case, it was not for some reason and from a dead stop, engaging the 
engine in reverse delivered a strong force to either port or starboard--can't 
remember which. It acted like I was using a stern thruster! Once I gained some 
water flow over the rudder, I could compensate for this force--but I had to be 
moving at a few knots. And as long as I kept her moving with short burst of 
thrust, I could control her direction.

OTOH, maneuvering in close quarters in reverse was impossible--thus my 
preference for stern to docking In reverse and subsequently bow out leaving any 
slip. 

Perhaps the term prop walk is incorrect--actually I should have called it prop 
offset.

I'm a bit puzzled by the talk about prop walk and offset shafts.
 I've found that prop walk is pronounced when the shaft is on centerline, but 
when the shaft is offset, it is offset to minimize prop walk. i.e. If the prop 
pulls to port, then the shaft is offset to starboard cancelling the effects of 
the prop walk in reverse. At least, that's how it should be done. Obviously, 
others here are experiencing things differently, which I find surprising.
