I figure it was shown to add some gravity to Impulse's situation. The Cave was still destroyed despite his attempts, so it was possible for the narrative that he'd fail his mission.

When all's said and done, that's not the case, but it was made possible by showing that.

I'd much prefer they leave timetravel alone for the next season at least. It gets messy.
