Right, it is reduced in the case of splitting the decice, see ?par and 
its section about "mfcol" as the posting guide asks you to do before 
posting:

     In a layout with exactly two rows and columns the base value
           of ‘"cex"’ is reduced by a factor of 0.83: if there are three
           or more of either rows or columns, the reduction factor is
           0.66.
