OK, I checked the g77 manual.

For XOR, we have 

   XOr(I, J)
   XOr: `INTEGER' or `LOGICAL' function, the exact type being
   the result of cross-promoting the types of all the arguments.

   I: `INTEGER' or `LOGICAL'; scalar; INTENT(IN).
   J: `INTEGER' or `LOGICAL'; scalar; INTENT(IN).

For IEOR form F95 Standard, we have

     13.14.46   IEOR (I, J)
     Description.   Performs an exclusive OR.
     Class.         Elemental function.
     Arguments.
        I           shall be of type integer.
        J           shall be of type integer with the same kind typer
                    parameter as I.
     Result Characteristics. Same as I.

So, the semantics are different with respect to LOGICAL.  I rework
your text to note this distinction.
