Oh wow ;-)
For the record, /bin/ is simply mapped to /usr/bin/. They are not
different directories, really.

Right. The difference between executables in /mingw64/bin/ and in
/usr/bin/ is that the latter executables all implicitly link to
msys-2.0.dll, i.e. the POSIX emulation layer based on Cygwin. As you
probably guessed: the coreutils are all compiled using that POSIX
emulation layer.
Ciao,
Johannes
