Yes its harder. Ok its been a LOONG time, but if I remember correctly: The way I read the algorithm, and if I understand what you mean by "dripping": to keep both branches "alive" in a node, you need to keep them within the "parking" range. Giving some blocks to the nodes (but not all of them) — "dripping" your blocks — keeps both chains within the "parking" range until you can force a split at the finalization depth.
