It's a very good way to save your finger moves. Swiping takes a lot more efforts than tapping. Each time you tap it, it scrolls down exactly one screen page. It's like you press the space bar when browsing on a laptop/PC.

This feature was introduced because people complained that too many swiping was needed. You don't need to use it if you prefer swiping.
