Error in code line 105 and 112 of simple.layout.scss

The code and comment don't match, the code defines the span as 8 but the comment says it's 12.

.two-sidebars {
.l-content {
@include span-columns(8, 16); // Span 12 out of 16 columns.
@include push(4, 16); // Push element by adding 4 out of 16 columns of left margin.
}
