This is, of course, completely expected (notwithstanding the confusion
caused by the "bitness" names being opposite of what some expect).

This is completely sensible and expected, as the entire point of the WoW
emulator is to emulate 32-bit Windows.

"Sysnative" isn't an actual file system directory, as noted, but an "alias"
(for lack of a better word) that allows, from a Wow64 process, to refer to
the real 64-bit system directory. You can use the name "Sysnative" if you
are certain you really want to refer to the 64-bit system directory.

This all seems like a pretty straightforward and sensible approach, IMO.
