I am confused. I too am right dominant so unclip (usually) on the right. I then, before light changes, move the left pedal (still clipped) to a 1 pm position so I can clearly push down on that side. When the light changes, I push off with the right (strong leg) and simultaneously pedal with the left. The two together give me enough momentum to move forward, flip right pedal over and clip in in time to do the right pedal stroke.
