I think there is a fundemental misattribution where the author talks about monolingual speakers. Speaking to non-native speakers in a language is a seperate skill that can be learned without proficiency in a second language. It takes skill and care to keep your sentence structure simple and independent of semantic nuance or idiom. People for whom English is a lingua franca have almost exclusively used English to speak to other non-native speakers and have lots of practice doing this.
