The address following the CALL/GOTO is relative by default to the
page the instruction is in

eg, the LST file shows

0014   0000           00046 MAJORT   NOP
0015   0FA0           00047                   INCFSZ   MPS_LO,F
0016   2814           00048                   GOTO     MAJORT
0017   0000           00049                   NOP

the GOTO will jump to 0014 of this page. Change to page 3 in
PCLATH and it will jump to 0014 in page 3. The whole 13-bit
address is popped off the stack if it had been a CALL, which
includes the PCLATH bits of the original CALL page
