I think the benefit comes from exercising(training) the brain to identify/translate/transmit sensory data (video/audio) faster. It's like having a conversation with an 80 yo grandma vs. talking to a fast witty talker. The brain needs to adjust to the word rate. I think this is one way to develop speed "on your feet" as the saying goes.
