While you're not exactly wrong (especially in the case presented), there are a variety of exceptions, for a loose definition of 'work' - which some future readers/searchers here might find useful. For example, if you're manning a booth at an exhibition for your foreign employer, that's work but allowed. Selling, being a service engineering, training, and some other things are also allowed with very careful restrictions.
