Having two branches in the same `if` structure with the same implementation is at best duplicate code, and at worst a coding error. If the same logic is truly needed for both instances, then they should be combined.

## Noncompliant Code Example

    IF var BETWEEN 0 AND 10 THEN
      do_the_thing();
    ELSIF var BETWEEN 10 AND 20 THEN
      do_the_thing(); -- Noncompliant; duplicates first condition
    ELSIF var BETWEEN 20 AND 50 THEN
      do_the_another_thing();
    ELSE
      do_the_rest()
    END IF;

## Compliant Solution

    IF var BETWEEN 0 AND 10 THEN
      do_the_thing();
    ELSIF var BETWEEN 10 AND 20 THEN
      do_the_second_thing();
    ELSIF var BETWEEN 20 AND 50 THEN
      do_the_another_thing();
    ELSE
      do_the_rest()
    END IF;
