Why should we do that? Also as we're including the svg via an @include I'm not sure of the difference.

So that we can use this icon on other places as well. If we have this icon in Images directory, we can use this icon on different places by just including the icon in twig or adding as background-image.

By the current scenario we need to duplicate the icon on different places. Hope this answers.
