Yep. This is similar to the way ring circuits work, and those were done for the exact same reason: saving on copper. I lived in a building where all the light switches and outlets were inexplicably wired in series, and it was super fun how any time anything went wrong there would just be no power til maintenance came and fixed it.

Or any component along the daisy chain.

Had a similar issue with an old Passat where the head unit was wired inline with the dome lights and when the bulb burnt out the radio stopped.

Was probably a homegamer job though
