As I understand this (someone pipe up and correct me if I'm wrong) the rod stays in to act as a support in case the Thorite breaks. The idea of using Thorite alone would work in theory, so long as the Thorite never breaks. If you pulled the rods out after drying, stuck the pillars in the tank, and one of the Thorite bonds broke, the whole pillar could come tumbling down, crash through the tank = instant flood. I see the rods as insurance.
