Some nested trips do break fare rules — but you won’t run into any issues unless it is repeatable and intentional.
There are some that just happen because you book something and then something else comes up. DL doesn’t really care as long as you aren’t engaging in repeated fraud in booking your nested tickets.
They are typically looking for someone who is repeatedly traveling to the same place and takes advantage of something like a Saturday-night stay requirement but then ladders in flights back to their origin to drive the overall price down
