Simple sort command

Below is a command
    sort -t: +2n myfile
I know it will sort the 3rd field numerically


Now I have this
    sort -t: +2n -3 myfile
I see this in my textbook but then what is the use? I don't understand :(

This syntax is used to specify a range of positions on the line.
Specifically, it sorts numerically on the character in position 2.

From the sort man page:

+POS1 [-POS2]
              Specify  a  field within each line to use as a sorting key.  The
              field consists of the portion of the line starting at  POS1  and
              up  to  (but  not  including) POS2 (or to the end of the line if
              POS2 is not given).  The fields and character positions are num-
              bered starting with 0.
