You are getting yourself confused with this specific emulation argument.
The definition: reproduce the function or action of (a different computer, software system, etc.)
The 68020 is a real cpu, a piece of hardware which is backward compatible with the 68000 another piece of hardware which exists. The 68020 is a different cpu a compatible continuation of the 68000 line so it doesn't emulate it as it is superseding it.
The FPGA version is imitating a piece of real hardware in it's entirety therefore it is emulating it. The whole point of it's existence is to mimic a real physical cpu which is not contained within it. This fits the exact definition of emulation in computing terms.
