I initially didn't add it as it'd never be used. You're right, though, and it's better to just have it there for consistency.

$is_person is never set

(At $employer we had the convention to always use !== null instead of isset when you expect the variable to exist to catch these kind of errors. empty() was also discouraged for this reason)
