OK, this will help what I'm understanding:
Is this:
tl3.pause()
.addLabel("start")
.to("#dot1_center", 1.5, {scale: 4, y: -15, x: -15, repeat: 0, ease: Elastic. easeOut.config( 1, 0.3)}, "start")
.to("#dot1_close", 1.5, {fill: "white", repeat: 0, scale: 4, y: -9, x: -9, ease: Elastic. easeOut.config( 1, 0.3)}, "start");
tl3.reverse();
the same as this:
tl3.pause()
.addLabel("start")
.to("#dot1_center", 1.5, {scale: 4, y: -15, x: -15, repeat: 0, ease: Elastic. easeOut.config( 1, 0.3)}, "start")
.to("#dot1_close", 1.5, {fill: "white", repeat: 0, scale: 4, y: -9, x: -9, ease: Elastic. easeOut.config( 1, 0.3)}, "start")
.reverse();
