If the latter, its effect as a valve lubricant may possibly be folklore but may be derived from the fact that it doesn't necessarily vapourise or get burnt. What it definitely does do is scour the oil from cylinder walls on intake and compression with accelerated ring and bore wear; the advice from the Chief Chemist at the Ass. Octel Co. in the UK is don't.

We use white kerosene, which we use in things lke torpedo heaters. It is a cleaner version of diesel fuel. Not exactly cheap either, it was priced a bit higher than gasoline. I haven't bought any in a few years, but have to get a gallon today when I get to town to run the reddy heater.
FIrst I heard of the cylinder washing problem. We used to use a light grade of diesel while fogging the engine to preserve gasoline velicles for long term storage. Hard to believe the kerosene, which is a lighter grade of diesel, could cause problems.
We use the term Naptha on this side of the pond when talking about campstove fuel, and mineral spirits when talking about the solvent you use to was parts in. I guess we shoud pull out our NATO STANAG conversion charts and talk in mil-spec codes so we can all be in the same language.
