He's right.  The mount point handling in Cygwin is based on the
in-memory mount table.  There's no reasonable way to fake some
reparse point to look like a mount point.  We can either handle it
as normal dir, or as symlink.  Handling it as normal dir is 
problematic in terms of find/rsync etc, bacause the cross-device
check would fail and files are potentially visited multiple times.
