Yeah, I mean I don't think there normally are so many lost brood creatures scuttling about under the enemy's nose (and if there are they are best handled by other methods like teleporting Lictors).
edit: not saying that it's a bad explanation, of course. And in any case good rules with a little stretched explanation are preferrable to bad ones based on very good fluff (*insert a standard dig at 40k here*).
Well... given the spawning rules and the elimination of 'nids outside of command, what we're basically saying is that we're keeping closest track of the synapse creatures, and only tracking the brood creatures that serve as a relevant body guard.
As a kind of background noise, the chittering hordes are always there -- and providing more than occasional target practice for their opponents -- but it's only when the synapse creatures get close that they act in coordination and pose a real threat.
