 Present editions of the '97 code have a provision that allows the use of a
 single 2x sole plate for shearwalls > 350 plf,   if  the required anchor bolt
 spacing is doubled.

Can someone explain the rational for this.  Why does putting more bolts in 
the sill plate solve the problem which I thought was splitting of the sill 
plate (by adding more bolts, less force per bolt for bearing on the sill 
plate?) and concerns about close nail spacing for highly loaded walls and 
cross grain bending of the sill plate at the holdown due to the anchor bolts.
