I doubt the flag is relevant, but going by some early draft it should
be the same as
pict_type == FF_I_TYPE || pict_type == FF_B_TYPE
in which case there would be no point in exporting it.
To test, you should at least use one of the interlaced VC-1 samples,
otherwise I think that code won't even be reached...
