Ryan,
Try reading the selection this way: Section 250.104(A)(1) requires the 'interior metal water piping system' and 'any other metal piping systems likely to become energized' to be bonded to the service equipment or grounding electrode conductor.
As opposed to: Section 250.104(A)(1) requires the 'interior metal water piping system and any other metal piping systems' likely to become energized to be bonded to the service equipment or grounding electrode conductor.
The first way is the way these two systems are worded in the NEC, the second is not.
To make it perfectly clear: The NEC requires bonding of "interior metal water piping systems" and of "other metal piping systems likely to be energized". Neither the NEC nor the Commentary refer to "interior metal water piping systems likely to be energized".
