There is no relationship between 0Ch and 08h. 
Read the datasheet again :

"  The GPR addresses in bank 1 are mapped to         "
"  addresses in bank 0. As an example, addressing    "
"  0Ch or 8Ch will access the same GPR.              "

0Ch and 8Ch map to the same register. (it *is* the 
same register, in fact). This is true for all the 
registers 0Ch - 2Fh, that map to 8Ch - AFh
