Furring strips and notching/holes

Iím in the middle of my bathroom Reno and I noticed that the backside of the wall Iíve torn out has furring strips attached to the entire backside of the studs. How does this work with notching and making holes in the studs? Are the furring strips considered part of the entire thickness of the stud?

The code is the hole needs to be 1 1/4" from the edge. As far as I know the furring strips counts as this edge as well.
This is to prevent screw or nail from driven into the wire while installing drywall or other wall finishing material.

That is national electric code... and is correct, but as far as wall framing codes are concerned, the furring strip is not even there. It is not structural and is not part of the stud.

Wet walls require a 2x6 wall when the size of the hole or notch in either the stud or the plates exceeds code limits.

R602.6... non-load bearing interior walls... holes can be bored up to 60% of stud width, holes no closer than 5/8" to stud edge. Notches not to exceed 40%. Exception: approved stud shoes may be used, following mfg instructions.

Example: https://www.amazon.com/Simpson-Stron.../dp/B001I3OZVI

Up to 2 3/8" o.d.
