It does not have an own paragraph in the userguide, but in the colors section you can read about the indicator.

The indicator color is used for indicating where a new window will be opened. For horizontal split containers, the right border will be painted in indicator color, for vertical split containers, the bottom border. This only applies to single windows within a split container, which are otherwise indistinguishable from single windows outside of a split container.
