[1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...

In addition to the central contact point, many cameras have additional metal contacts within the "U" of the hot shoe. These are proprietary connectors that allow for more communication between the camera and a "dedicated flash".
When using rear-curtain flash (when the flash fires at the end of the exposure) and a slow shutter speed, the distinction between the main flash and the preflashes is more obvious.

Either the flash is firing too late or the shutter speed is too fast (shutter moving vertically). Note the different exposure levels. In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.
