A sane assumption is for instance, if you cd to foo, that your in foo.
That's what the FSR breaks in a thorough way.  I. e. on WOW64:

  $ cd /cygdrive/c/Windows
  $ ls -1d Sys*
  SysWOW64
  System
  System32
  SystemApps
  SystemResources

So there are two dirs, one called System32, one called SysWOW64.
Note how there's *no* such directory called "Sysnative".  Still...

  $ cd System32

works fine.  You're just not in System32, but in SysWOW64.  Sane?

Alternatively:

  $ cd Sysnative

works fine and now you're, oh wonder, in System32.  If that's sane,
running head first into a wall is, too :)
