RX65N - section switch? RESETVECT

I understand the the reset vector for RX65N is always allocated to 0xFFFF FFFC (as in the Hardware User Manual)

But I have seen RX65N program which has its sections allocated like below, and it works:

SI,B_1,R_1,B_2,R_2,B,R,RPFRAM2/04,......,C_1,C_2,C,C$*,D*,W*,L,P*/0FFF00000,EXCEPTVECT/0FFFBFF80,RESETVECT/0FFFBFFFC

And in vecttbl.c:

#if defined(__CCRX__) || defined(__GNUC__)
R_ATTRIB_SECTION_CHANGE_RESETVECT void (* const Reset_Vector[])(void) =
{
    PowerON_Reset_PC                   /* 0xfffffffc  RESET */
};
R_ATTRIB_SECTION_CHANGE_END
#endif /* defined(__CCRX__) || defined(__GNUC__) */

Can anybody explain why?
