You are both right.  The last word of program memory contains a RETLW
instruction.  This takes up a whole program memory word, but the data is one
8 bit byte.  Of those 8 bits, only the high 6 are actually used in the
current implementation.  The low 2 bits written to the OSCCAL register are
ignored.
