    You want storage tank stratification for best and most efficient use. You also get more hot water with less energy.
    @hot_rod can explain it much better.

    It would depend on the water heater.
    A coil type indirect if they were reversed may have some/ little performance issues. At one point HTP on their Contender WH had the install diagram listed one way and the photo in the same book listed the opposite.
    With a tank in tank set up there may be more of an issue.
    Why do you ask? Was your indirect piped "backwards"
