Having two branches in the same `@if ... @else if ... @else` 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 $x == 0 {
      do-something();
    } @else if $x == 1 {
      do-something-different();
    } @else {
      do-something();   /* Noncompliant: Same implementation as in the @if block */
    }

## Compliant Solution

    @if $x == 1 {
      do-something-different();
    } @else {
      do-something();
    }

    OR

    @if $x == 0 {
      do-something();
    } @else if $x == 1 {
      do-something-different();
    } @else {
      do-something-else();
    }
