Fine. So what? Just because it works doesn't mean it's perfect or frictionless.
Lots of software and business concepts are not simple. They take a long time to explain, and they're hard to express with a language (English) that was not designed to express them.
Like I said, it's a problem between two native English speakers, too. It's just more of a problem when one of those people is missing chunks of vocabulary or doesn't understand some of the small, impactful differences in wording in English.
My business partner is Israeli and speaks excellent English, and we still run into these problems sometimes.
