My guess is that your fuel lines are being emptied through the night. When you turn the key to the on position, it turns on the fuel pump for a moment. This brings your fuel back up to the rail, to the injectors, and builds up enough pressure in the line. If you did it twice, you'd get even more of a head start on getting the fuel line back up to an optimal state.
A tiny leak will cause these conditions, allowing the the fuel line to depressurize over long periods of time.
