There are 4 properties on this object

1. a boolean
2. a nullable string which is always set if 1 is true
3. a nullable string with is always set if 1 is false and sometimes set if 1 is true
4. a virtual property which is the null coalesce of 4 ?? 3

Logically 4 will always be able to return a set string but I cannot figure out how to get phpstan to recognize that properly
