Actually, I CAN understand why some electricians might think this was ok to do but in my area they would have to be about 75 years old at leastIn houses around here built up to the 1950s or 1960s, lighting circuits were run from 4" round to 4" round, with switches dropped out of each 4" round box. It was pretty much a given that the load on the switch leg was never going to be larger than a two lamp fixture. A single 20A circuit would handle the lighting load of most of the house, and #14 for the switch legs (loops) would save money without creating a hazard (back then...). Nowadays in resi we wire the feed to the switch which makes it possible to fully load a lighting circuit on one switch so it would be very bad practice to feed a switch with #12 and then feed the lighting with #14. But if someone works in an area where running the feeds to the ceiling boxes is still done, they probably wouldn't see any danger in using a #14 switch leg.
This is the strangest explanation I have ever seen.
