I wouldn't assume that _anything_ Cygwin does makes sense, or is
consistent with anything else.

Its attempts to produce UNIX-like behaviour on Windows cause some truly
bizarre behaviour at times.

It is not totally unfair to compare the level of weirdness of Cygwin to
that of WINE, though they operate in completely different ways. I
wouldn't suggest making any conclusions about the _other_ platforms
based on Cygwin.
