Yes, Win32/NTFS has a bunch of arbitrary seeming path restrictions, magic
normalisation and illegal names. A single or two trailing dot(s) are
one of the things not valid in Win32 namepsace, in this case due to
path normalisation.
(There are special ways to bypass normalisation, but chances are you’d
have trouble to interact with or even delete such a dir from Windows)
See:

and the relevant ntfs-3g option the mounting GUI probably uses:
