There are two pretend types:

- they move their official residence and happen to stay most of the time at the "totally just rented" place in the same state anyway

- or keep telling everyone how they're going to move, but don't actually do.

Because let's be honest - if there wasn't a big reason to live where they do, and it wasn't a pain to work from another state, they wouldn't be there to begin with. They're paying the higher taxes because they benefit(ed) in some way.

They also benefit from being famous and threatening to leave.
