The situation you are talking about is called 'ground potential rise' and yes a close in strike can cause the ground potential to rise to very dangerous levels, and any conductive material (water pipes, plastic pipes with water, landscape lighting, ANY wiring, etc in this area can then conduct a surge into the house, this will NOT be protected by the SECO arrestor, or any arrestor installed in the circuit breaker panel. It can damage the first piece of equipment that it encounters, for example the water line to the refrigerator. Point of use protectors (UL 1449 I think) may provide some protection for some but not all of these types of surges.
