[jitter] @unique in qt.movie in a javascript - doesn't work?

...doesn't seem to work as advertised.
probably the easiest way to check this is trying the 
jitter-examples/javascript/video/jsmovieadapt-example.pat
and adding
mov.unique = 1;
after the var mov declaration.
even with unique on, I still get the max fps output, rather than the "unique-limited" fps of the movie.
Is there something I'm missing or does matrixcalc() on a jit.qt.movie not respect the unique attribute?
