[Discussion] Strange piece of logic

at lib/components/breadcrumb.vue found this piece of logic:

                  if (item.active !== true && item.active !== false) {
                         item.__active = item === last;
                     } else {
                         item.__active = item.active;
                     }

Can somebody explain me why to use such complex statement? item.active !== true && item.active !== false => true when item.active undefined or null? item.active !== true && item.active !== false => false when item.active is set ?

why dont just use item.active == null instead?
