Yes, you're right.
(Sorry for not trying exactly what you suggested right at the beginning...)

I just never realised since I am always using profiles, only changing 
options, but not directly specifying roots.

It also accepts the version::

   unison -root a -root b

which has the same problem, but it gives an error if you try::

   unison -root
   /Applications/Unison.app/Contents/MacOS/Unison: option `-root' needs 
an argument.

so the option parsing seems to be ok.
I would guess the feature is simply missing from the Mac GUI?
