I have worked on simulators for most of my life and the GPs definition is not true. There's no formal distinction between the two, but conventionally emulation is more faithful whereas simulation is more high-level. Still, the two are used fairly interchangeably.

To me the distinction seems obvious: simulation reproduces the external behaviour of a system i.e from observers pov; emulation reproduces the internal behaviour. Typically the external behaviour emerges from this as a matter of course, but in many cases such a “bottom up” approach isn’t possible or even necessary.
