As I mentioned confusion abounds.
The bond for the CSST at the point nearest entry into the building is for lightning.
The grounded wire to any gas appliance that also has electric, for motors, igniters, etc. provides the required bond for NEC purposes.
Bits or pieces of metal piping in the gas system, Tees, manifolds, fittings do not constitute a piping system and do not need to be bonded.
Usually the gas piping outside the building is not metal. That is another reason for not using the gas line as a grounding electrode.
Remember the CSST bond is for lightning, which can travel through the earth regardless of any metal pipe path.
Note; I was registered years ago, but re-registered when I changed computers.
