Because it is program memory, not RAM.
Remember in the PIC, two completely different memory spaces. The ram can be read with normal I/O operations, but the ROM has to be read using different instructions, and different addresses. So there is an address '0', in the ROM, and another address '0' in the RAM.

Best Wishes
