LTM8055 Parallel Operation


I have a few questions about the LTM8055.  The LTSPICE demo circuit for parallel LTM8055  found here shows a large voltage overshoot on startup and very high current demands from the modules.  Is this realistic of the modules in a parallel configuration or is this a simulation artifact?  The datasheet doesn't mention anything about parallel startup being a problem.   The single device LTSPICE model doesn't have this problem.  The simulation is for a 12V output and the voltage goes to almost 24V before settling.

Unrelated to the simulation, does the device have short circuit protection in all modes of operation (buck and boost)?  Do I need to do anything special for parallel devices for fault protection?  Do they have any circulating problems during faults?
