No, that’s entirely intentional.

The IP and manufacturing are linked because you can’t manufacture something from commercial sale if you don’t have patent rights.

But the licensing of patent rights was done for tax advantage in the EU, not the US (generally).

Taxes are important but not the sole determinant of where they manufacture.

The manufacturing is in one place. The IP in another place. Both places chosen mostly for tax reasons in this case. Paying zero taxes in the US is a lucky side-effect.
