The TTL auto flash exposure system of digital SLRs fire a low powered pre-flash before the shutter opens and the mirror flips up. This pre-flash is measured by the camera's meter to determine the actual flash power needed when the shutter is open (the second flash). With 1st curtain sync the 2 flashes are so close together that they are perceived as a single flash. With 2nd curtain sync it is easy to see the 2 separate firings.
