What's the point of naming grid lines?

Hi guys; so here's some code:

<div class="wrapper">
  <div class="item1">Start column line 1, span 3 column tracks.</div>
  <div class="item2">
    Start column line 6, span 4 column tracks. 2 row tracks.
  </div>
  <div class="item3">Start row 2 column line 2, span 2 column tracks.</div>
  <div class="item4">
    Start at column line 3, span to the end of the grid (-1).
  </div>
</div>

<div class="wrapper">
  <div class="item1">Start column line 1, span 3 column tracks.</div>
  <div class="item2">
    Start column line 6, span 4 column tracks. 2 row tracks.
  </div>
  <div class="item3">Start row 2 column line 2, span 2 column tracks.</div>
  <div class="item4">
    Start at column line 3, span to the end of the grid (-1).
  </div>
</div>

.wrapper {
  display: grid;
  grid-template-columns: repeat(12, [col-start] 1fr);
  gap: 20px;
}

.item1 {
  grid-column: col-start / span 3;
}
.item2 {
  grid-column: col-start 6 / span 4;
  grid-row: 1 / 3;
}
.item3 {
  grid-column: col-start 2 / span 2;
  grid-row: 2;
}
.item4 {
  grid-column: col-start 3 / -1;
  grid-row: 3;
}

.wrapper {
  display: grid;
  grid-template-columns: repeat(12, [col-start] 1fr);
  gap: 20px;
}

.item1 {
  grid-column: col-start / span 3;
}
.item2 {
  grid-column: col-start 6 / span 4;
  grid-row: 1 / 3;
}
.item3 {
  grid-column: col-start 2 / span 2;
  grid-row: 2;
}
.item4 {
  grid-column: col-start 3 / -1;
  grid-row: 3;
}

So my question is, whats the point of naming grid lines when I can just use the line number itself? Instead of

.item3 {
  grid-column: col-start 2 / span 2;
  grid-row: 2;
}

.item3 {
  grid-column: col-start 2 / span 2;
  grid-row: 2;
}

Why not just omit col-start and do this:

.item3 {
  grid-column: 2 / span 2;
  grid-row: 2;
}

.item3 {
  grid-column: 2 / span 2;
  grid-row: 2;
}

With a repeat, it doesnt make much sense, because all grid lines will get the same name, but when you give each column separate line names, you can assign childs easier (specially with overlapping regions), here a wonderful example (not mine) https://codepen.io/hexagoncircle/pen/dyejrpE

following up on this. what is the advantage (if there is any) of naming grid lines over using grid-template-areas with named areas?

Overlapping content, for one. Named areas can't overlap other areas. With line names, you can easily overlap content.
