Quite  often the strings change direction toward their respective tuning pins 
enough  that the string tension will rotate the agraffe to find its best 
balance  between the sideways string pressures.
As I am doing right now on a Steinway A2, I typically seat the agraffe  to 
bisect the angle to mitigate the turning "moment" of the agraffe with strings  
that are not straight from the speaking length to the tuning pin, especially in 
 the monochords, rarely in the bichords. I can see how a serious bichord 
offset  would cause a rotational force, however.
