Never.
You cut off the part of the quote that said "designed, installed, owned, maintained, and paid for by" the customer. Anything meeting that description is the customer's, and so is on the customer side of the service point.
Agreed that the pole is the POCOs (I assume, anyway not the customer's), and so the wire and conduit on the pole seems like it has to be on the utility side of the service point. Maybe the service point is where the wire and conduit enter the ground, or at the edge of the lot. Regardless, I don't think PNM's use of the phrase "point of service" means the same as the NEC's "service point."
