The 'rear' engine could be started using its prop as it windmilled in the airflow generated by the front engine and its prop...
The interesting bit is that both engines drive a prop on the same axis.
This is a counter rotating propellor assembley, not a contra rotating propellor.

To further expand on the concept:
Contra-rotating propellers, also referred to as coaxial contra-rotating propellers, apply the maximum power of usually a single piston or turboprop engine to drive two propellers in opposite rotation
