I am not sure you are reading that correctly. It's a bullet point letter not actual language. Most pilots not living in Minneapolis claim for tax purposes they don't live or work in the state. A pilot domicle is not under most legal definitions a place of work. Claiming you do work in MSP might lead to some unwanted tax effects. I have no idea what Delta's policy on this is however I suspect they have full researched it.
The best option is to go for a me too clause in the contract.
