Please show a short Org file where this function returns nil on
Windows, but non-nil on GNU/Linux.  (Are you testing this in the same
Emacs version on both systems, btw?)

I don't see any bug there, just explanations why Ryan's implementation
was wrong.

Are you using the version of Org that came with this version of Emacs?
Or are you using a different version?
