I've got a composition that does something similar. I've got a video
input that feeds a chain of 2 coreimage filters and also feeds a
gaussian blur. The 2 results combine in a luminosity blend which
outputs to a billboard. At first I noticed similar behavior to what
you've mentioned... that only one of those pre-blend 'chains' (for
lack of a better term) made it to the billboard. I found that the
fix for this was to swap which input in the blend each chain fed.
Pretty simple but nifty. Now I just have to get it to do more than
2fps on my G5.

i've noticed an unexpected behavior in quartz composer - tell me if
i'm imagining things:
when i connect two patch networks to a multiplexer - and then feed
that into a billboard - composer "knows" to only evaluate only the
one network which contributes to the final result.
but if i put that multiplexer into a macro (simply by publishing
all it's inputs and outputs) then composer does NOT "know" to only
evaluate one network. it evaluates both.
