Nope, says nothing like that. You're close, but the devil is in the detail of the text.
Are you aware of how wiring is run on roofs where there are exposed beams with tongue and groove roof decking exposed inside? Permit me to explain. The roof is framed up. The tongue and groove boards are laid on top of the roof framing. The wiring is affixed on top of the roof decking. One to several inches of insulation board are laid on top, with grooves cut as necessary to eliminate pressure on the wiring. The roof gets the BUR or EPDM system installed. In this case, the OP had a BIR, and added a layer of plywood on top with some other roofing system installed. The long nails necessary to affix this plywood obviously pierced some of the wiring.
