What does 'in a single asm stream' means?

It really seems to me that you have two streams at the lowest level, 
along with the knowledge of how many samples to remove/insert and hence 
could do a much better job - including gapless support between unrelated 
profiles and cross-fading - without the partial drain and next_track 
mechanism that was defined assuming a single stream/profile.
