Actually, no.  In many intersections the only break in traffic allowing a left turn is when the light is yellow, or even red.  That means the person who pulled into the intersection while waiting for room to turn is the only one who made it over the limit line before the red.  The 2nd or 3rd car will be going through on red (which they still do).  And this works ONLY if oncoming traffic actually stops on yellow instead of running the red.
