The percentage of the salt used is in comparison to the maximal concentration of the salt in the mixture can dissolve. 
As such, although high concentrations are needed for the method to work adding an abundance of the salt, over 100%, can also oversaturate the solution, therefore, contaminating the nonpolar precipitate with salt precipitate.
