1. Combine sugar and 1/2 cup water in a small saucepan; bring to a boil, stirring constantly. Boil 30 seconds, remove from heat, and let cool 5 minutes.
2. Mix 1/3 cup sugar syrup with the pomegranate juice. In a separate bowl, combine the remaining 1/3 cup sugar syrup, 1/3 cup water, and orange juice concentrate.
3. Fill 8 pop molds 1/3 of the way with pomegranate mixture; freeze 1 1/2 hours. Remove molds from freezer, add orange juice mixture, leaving 1 inch of the mold empty, and insert the pop sticks; freeze 1 1/2 hours. Remove pops, and add remaining pomegranate mixture; freeze about 1 hour or until firm. To reverse the color order, start with the orange juice mixture, follow with pomegranate mixture, then orange juice mixture.
