How does this work if you use multiple iOS clients with the same nsec?

Example; I create an account on Damus, and connect to my Lightning node to send and receive zaps. Then I download Primal and sign in with the same nsec. Does it create a new wallet and tell my relays to override my previous settings? I recall maybe a year ago, putting your nsec into a new client could scramble your relay list, but haven’t thought about it from an “inbuilt wallet” perspective…
