If the string offset angles were kept the same as for a standard 
pinned bridge (say 10 -12 degrees), the double string offset will 
increase the overall resistance to the ease of rendering, as you are 
probably thinking (though as such it need not be detrimental to 
tuning stability). Unless the offset angle is reduced, in the case of 
the double offset agraffe, there will be an increased propensity to 
pull the bridges over. However, the latest agraffe design (from this 
manufacturer) is much improved over the first version in this 
respect. The first version, while it had only a single string offset, 
subjected the bridge to a significant forward rotation force. See 
image below;
