If you use an adapter to accommodate plugging your 30amp shore power into a 50amp circuit you have a shore cord rated for 30amps "protected" by a 50 amp breaker. Not effective protection.....
The 30A main breaker in the RV keeps it from pulling more than 30A through the cord.
So he is protected.
Since he mentioned only the cord, the statement is correct. While it is very unlikely that the 30 amp cord will ever be overloaded, breakers are for unlikely events such as a short circuit or being used improperly such as connecting it to a higher load.
