Almost, but not quite. It does apply on all flights departing from the EU, but only on flights arriving in the EU if they are operated by a carrier from an EU country. It's a small but important distinction. For example, if you were travelling from London to New York, it would always apply regardless of the airline. In the other direction, however, it would apply on BA but not on AA.
