It could be intended, however whilst testing out husk and stray spawned eggs I found that once the husks and zombies targeted a villager they would keep going after that same one even if there are others nearby. After re-logging into the game the group split up and started following nearer villagers then continued to ignore others again. So simply, they only update to the nearest villager when entering the game.

Edit:
Zombies and husks ignore target villager once they move far enough away, likely 40 blocks
