FVWM: Next/Prev question

I am hitting a mental block in reading the section of the fvwm man
page on Conditional Commands.

We read:

    Next [(conditions)] command
        Performs command (typically Focus) on the
        next window which satisfies all conditions.

    Prev [(conditions)] command
        Performs command (typically Focus) on the
        previous window which satisfies all conditions.

My question is: when should I use Next and when should I use Prev
in a script?

For instance, let's consider the following example from the man page:

   AddToFunc MailFunction
    + I Next ($0) Iconify off
    + I Next (AcceptsFocus, $0) focus
    + I None ($0) Exec exec $0 $1

Why is Next used here? Why not Prev? What's the difference?
