[vorbis-dev] Are vorbis_blocks really independent?

I can answer this question myself. I have an array of N vorbis_blocks. Now
the results of

for(i=0; i<count; ++i) {
    vorbis_analysis(&vb_buffer[i], &op);


for (i = count-1; i>=0; --i) {
    vorbis_analysis(&vb_buffer[i], &op);

Are _exactly_ the same. So I guess they are really independent :-) Sounds
promising, doesn't it?
