It is indicated by the blue curved line in the graph below:

{{{drawing(400,400,-5,5,-5,5, graph(400,400,-5,5,-5,5),line(0,0,2,-2sqrt(3))
blue(arc(0,0,2,2,0,60) ), blue(arc(0,0,2.2,2,60,180) ),
blue(arc(.1,0,2.3,2,180,360) ), blue(arc(0,0,2.4,2.5,0,60) )

)}}} 

Notice that -420° means 420° of rotation in the clockwise
direction. 

You start at about the point 1 on the x-axis.  Then you swing around
420° clockwise as indicated by the blue curved line.  420° is more
than 360° so it's more than one swing around, for it swings around
one whole turn and ends up in the fourth quadrant 60° below the x-axis
because 420°-360°=60°
